1.  Introduction
This reference manual provides concise descriptions of the command input requirements for
the ADINA User Interface (AUI).  This introduction serves to give some background informa-
tion and indicate the general command syntax including descriptions of the conventions
used.
1.1  Program execution
Commands can be entered in the following modes:
Interactive
(a) AUI is running with the user interface displayed  you can enter commands into the user
interface command window  see the AUI Users Guide.
(b) AUI is running in command mode (using the "-cmd" option)  you can enter commands
from standard input.
Batch
(a) AUI is running with the user interface displayed  you can read commands from a file by
choosing File→Batch (UNIX versions) or File→Open (Windows version)  see the AUI
Users Guide.
(b) Commands can be read from a given file using the aui startup options -s (UNIX versions)
or -b (Windows version).
You can also read commands from a file using the READ command (see Section 3).
1.2  Command syntax
Here is the layout of a typical command reference page:
COMMAND[1] PARAM1  PARAM2[2]...
data1i  data2i
[3]...

Auxiliary commands[8]
LIST COMMAND
Brief description of this command.
DELETE COMMAND
Brief description of this command.
Issuing a command allows you to alter the data associated with the command.  This data
comprises the values associated with the command parameters and possibly a table, input via
"data lines", associated with the command.
In the above, the command name "COMMAND"[1], given at the top of the reference page,
has the first few characters emphasized to show the minimum number of characters required
to be input to uniquely identify the command.  A list of parameters[2] and data lines[3] for the
command then follows.  In this list the first few characters in the parameter and data line
names are emphasized to show the minimum number of characters required to uniquely
identify the parameter and data line names.
Following a general outline of the command function[4], a description of the command
parameters and data line entries is given below the relevant keynames[5].
The parameters usually have default values[6] which are assumed if the parameter is not
explicitly specified.  The default values are indicated in brackets [  ]  a bold value indicates a
default value (number or string) and an italicized string indicates the source of the default
value, which is either (a) a text description of the default, (b) a parameter name from the same
ADINA R & D, Inc.
           1-5
command, or (c) a combination of command + parameter names, indicating that the default is
taken from the setting of another (different) command parameter.
A parameter for which no default is provided means that there is no default  i.e., some choice
must be entered for that parameter.
One important parameter type is that of an entity identifier  for which the parameter keyname
"NAME" is normally reserved.  If the object identified by NAME has already been defined,
then the other parameter defaults are set to the previous settings for that object.  If a new
NAME is given then the defaults, as indicated by the command reference pages herein, are
taken.  In the former case, execution of the command redefines the named object.
The choice of parameter values is often discussed within the parameter description, but,
where appropriate, a simple list of choices follows the parameter description[7].  For example,
parameters with simple logical choices will have the list "{YES/NO}" appended to the
description.
When a table is associated with the command, the command includes data input lines.  For
some commands, the table is initially empty, but for other commands the table already
includes data lines.
The columns of a data line can be divided into two types: key columns and data columns.
When a data line has key columns, the key value columns always precede the data value
columns.  In this case the values of the key columns uniquely identify the data line, and,
therefore, two data lines cannot have the same key column values  for such input, the
second input data line overwrites the data associated with the key column values.
You can delete a data line by preceding the key column values with the DELETE prefix.  When
a data line does not have key columns, two or more data lines can have the same values  but
you cannot use the DELETE prefix to delete data lines without key columns.  However, you
can always delete all of the data lines of a table using the @CLEAR or CLEAR keywords.
This is of course especially useful for those tables in which there are no key columns.
For data line input, not all the columns need be specified; the ENTRIES keyword, which can
be input as the first data line following the command line, can be used to select a subset of
the data column entries (see below).  Then the values you enter in the subsequent data lines
are associated with the columns indicated by the ENTRIES parameters, the other data
columns taking default values whenever possible.  Note, however, that key columns are
required input, and should thus be included in the ENTRIES column list.
Many commands have "auxiliary" commands[8] which are entered with one of the following
prefixes:
Sec. 1.2 Command syntax
1-6
AUI Command Reference Manual: Vol. III  ADINA CFD Model Definition
Chap. 1   Introduction
LIST
List object definitions.
DELETE
Delete objects from the database.
UPDATE
Update command defaults.
RESET
Reset command defaults.
COPY
Copy objects.
SET
Set "currently active" objects.
SHOW
Show "currently active" objects.
A LIST prefixed command has several forms:
LIST COMMAND
List all object identifiers (names).
LIST COMMAND NAME
List definition of object with identifier NAME.
LIST COMMAND FIRST LAST
List definitions of a range of objects with integer
label numbers. Parameters FIRST, LAST may
also take the string values FIRST, LAST,
ALL.
A DELETE prefixed command has the following forms:
DELETE COMMAND
NAME
Delete the object with identifier NAME.
DELETE COMMAND
FIRST LAST
Delete a set of objects with integer label
numbers in the specified range.
Note that an object may not be deleted if another model entity depends on its existence as
part of its own definition.  For example, a geometry line cannot be deleted if it forms a bound-
ing edge of some geometry surface.
1.3  Input details
Command input
Please refer to command AUTOMATIC LOAD-DISPLACEMENT in the following discussion
(Section 5.5):
AUTOMATIC LOAD-DISPLACEMENT
POINT   DOF  DISPLACEMENT
ALPHA  DISPMAX CONTINUE
RPRINT  TYPE NODE
When entering commands, only as many characters as necessary to uniquely specify the
command name need be entered.  The same rule applies to the parameters and data line entry
ADINA R & D, Inc.
           1-7
key names within a command. The minimum number of characters necessary are indicated in
bold.
Note that command / parameter is case insensitive.  All commands, parameters, values are
stored in upper case, except for string variables (headings, graph legends, etc.).
Parameter values may be input in any order if the keynames are used, e.g.,
AUTOMATIC LOAD-DISPLACEMENT DOF=3  RPRINT=YES  DISPMAX=5.0
DISPLACEMENT=4.0  POINT=17
Some or all of the parameters can be excluded if the positional order of the parameters is
observed, e.g.,
AUTOMATIC LOAD-DISPLACEMENT 17  3  4.0, ,5.0, ,YES
(the parameters ALPHA and CONTINUE have been omitted by the use of the commas).
A mix of keyname parameters and positional input is allowed, e.g.,
AUTOMATIC LOAD-DISPLACEMENT 17 DISPLACEMENT=4.0 DOF=3,,5.0,,
YES
The above uses of the AUTOMATIC LOAD-DISPLACEMENT command are all equivalent.
The omitted parameters in each case take the default values.
Data lines
Many commands require data line (tabular) input, e.g., MODAL-DAMPING (see Section 5.3):
MODAL-DAMPING
modei  factori
Use the ENTRIES keyword to select only the data columns that you want to enter (the other
data columns will be given default values):
MODAL-DAMPING
ENTRIES MODE FACTOR
1 1.0
2 0.5
3 2.5
4 1.5
DATAEND
Most commands which take this form of input also allow for incremental row generation via the
"STEP inc TO" option where "inc" represents an increment in the generation, i.e., in the above
Sec. 1.3 Input details
1-8
AUI Command Reference Manual: Vol. III  ADINA CFD Model Definition
Chap. 1   Introduction
example modei+k, modei+2k, ..., modej-k, are all generated, with the corresponding values for "factor"
linearly interpolated between factori and factorj.  When generating integer values, the difference
between the first and last values must be an integer multiple of the STEP increment (i.e.,
modulo((modej-modei),k) = 0).  There is a default step increment, which for integer values is
normally 1; in this case "STEP 1 TO" may be input simply as "TO". Here are some examples:
MODAL-DAMPING
1  5.5
TO
3  7.5
@
or
MODAL-DAMPING
1  5.5
STEP 1 TO 3  7.5
DATAEND
Both of these are equivalent to
MODAL-DAMPING
1  5.5
2  6.5
3  7.5
@
Note that data line input may be terminated either by entering the symbol "@" or the string
"DATAEND"  data line input will be terminated automatically by input of the next command.
Data line rows can be deleted by preceding the key value by the prefix DELETE.  This method
of deletion also supports row "generation"   i.e., "DELETE i STEP k TO j" may be used to
delete a range of values.
All the data lines associated with a command may be deleted simultaneously using the
CLEAR or @CLEAR keywords. This is useful when you want to define a table if you do not
know if the table is already defined or not:
TIMEFUNCTION 1
CLEAR
which removes all the currently defined data lines of timefunction 1.
The columns for data line input can be selected by use of the keyword ENTRIES in the first
input data line following the command line, e.g.,
ADINA R & D, Inc.
           1-9
COORDINATES POINT
ENTRIES NAME Y Z
which indicates that only global Y and Z coordinates are to be input for geometry points in
the subsequent data lines.  The X coordinate assumes the default value 0.0, and thus
subsequent data lines entered describe points in the global Y-Z plane.
Names
AUI names are usually of two types  alphanumeric strings of up to 30 characters or integer
label numbers.  Integer label numbers are normally greater than or equal to 1.
Integer values
Integers can be input with a maximum of 9 significant digits.  For positive values, a preceding
+ sign may, if desired, be input.
Real values
Specification of real values can include a decimal point and/or an exponent.  The exponent
must be preceded by the letters E, e, D, or d, e.g.,
2E5
2.0d+07
200000.
all refer to the same real number.
Alphanumeric values
Alphanumeric values must start with a letter (A-Z, a-z) or number (0-9).  The only permissible
characters allowed are the letters A-Z, a-z, the digits 0 to 9, the hyphen (-), and the underscore (_).
Lower-case characters in an alphanumeric value are always converted to upper-case by the AUI.
String values
A string should be enclosed by apostrophes (').  Any apostrophe within the string must be
entered twice.  Any character can be included in a string.  Lower-case characters in a string
value are not converted to upper-case.
Filenames
A filename should be enclosed by apostrophes (').  Filenames can be up to 256 characters
long.
Length of input lines
Input lines to the AUI can each contain up to 256 characters.
Line continuation, line separator, blanks, and commas
If the last non-blank character of a command or data line is a comma (,), then the command or
Sec. 1.3 Input details
1-10
AUI Command Reference Manual: Vol. III  ADINA CFD Model Definition
Chap. 1   Introduction
data is continued on the next input line.  The total length of an input line and all of its
continuations can be up to 2000 characters.
A slash (/) in an input line can be used to end a command or data input line; more commands
or data can then be entered on the same input line.
A blank, several blanks, <Tab> characters, a comma, or a comma surrounded by blanks act as
delimiters.  Commands, parameter keynames and values must be separated by delimiters.
Comments
Comment lines can appear anywhere in the input and are identified by an asterisk (*) in
column 1, e.g.,
* This is a comment line
Parameter substitution
You can define parameters as numeric expressions, and use the parameter values in later
commands. This feature is useful when creating batch files used in structural optimization.
For example:
PARAMETER A `5 + 7`
PARAMETER B `2*$A`
PARAMETER C `3 + $A + 4*$B`
BODY BLOCK DX1=$A DX2=$B DX3=$C
1.4  Messages
Commands will often echo messages confirming their successful completion, or provide other
information.  Otherwise you may get error/warning messages with varying levels of severity:
*** INPUT ERROR
You have entered an unacceptable parameter value or data.  The command will not
execute with invalid input.
*** WARNING
The command has completed, but has detected a possible inconsistency which may have
to be resolved.
*** ALERT
The command has completed, but has detected a definite modeling inconsistency which
has to be resolved in order to create a valid model.
*** ERROR
The command has not completed.
ADINA R & D, Inc.
           1-11
*** INTERNAL ERROR
The program has determined some conflict in the database, normally indicating a
software bug.  You should contact ADINA R & D Inc. if you encounter such a message.
In order to track down the source of the problem it would be most useful if the input
responsible for this condition is made available to the support engineers.
*** MEMORY OVERFLOW
The command has not completed, due to the program running out of memory. Increse the
memory allocation to the program
1.5  File input/output
The AUI uses several files for handling I/O.  Here is a brief description of some of them,
together with a suggested filename extension convention (for the UNIX operating system 
other filename conventions may be appropriate for other operating systems) :
<file>.in
ADINA-IN batch command input.
<file>.idb
ADINA-IN permanent database.
<file>.plot
ADINA-PLOT batch command input.
<file>.pdb
ADINA-PLOT permanent database.
<file>.ses
AUI session file (echo of command input).
<file>.ps
PostScript snapshot.
<file>.dat
Analysis data.
<file>.port
Analysis porthole.
<file>.out
Analysis printout.
See the AUI Users Guide, Chapter 6 for more information.
1.6  The AUI database
The AUI uses an internal database to store and retrieve data used during program execution.
The internal database is stored in main memory and, if main memory is not sufficient, a tempo-
rary database file is created to hold the excess data.  The internal database can be saved in a
disk file, called a permanent database file, so that it can be retrieved in a future run.
Five commands are used to create, open and save databases.  DATABASE NEW creates a
new empty internal database. DATABASE OPEN initializes the internal database using a
specified permanent database file. DATABASE SAVE saves the internal database to disk,
allowing you to specify the name of the database file.  DATABASE ATTACH causes the AUI
to use the specified permanent database file as the internal database.  DATABASE DETACH
renames the internal database file as a permanent database file.  All of these commands are
described in Section 3.1.
Sec. 1.5  File input/output
1-12
AUI Command Reference Manual: Vol. III  ADINA CFD Model Definition
Chap. 1   Introduction
The permanent database file is similar to a text file used in a word processing program.  Like
the text file, the permanent database file resides on disk and can be retrieved by the program
in a future run.  The permanent database file can be saved on disk periodically during
program execution to protect against loss of data due to computer failure.  During each save
operation, a different permanent database file can be selected so that several versions of the
database are available for retrieval.  (This is similar to saving several versions of a text file on
disk when working with a word processing program.) For the differences between DATABASE
OPEN and DATABASE ATTACH, see the command description for DATABASE ATTACH.  For
the differences between DATABASE SAVE and DATABASE DETACH, see the command
description for DATABASE DETACH.
1.7  Listings
Many AUI commands generate lists.  For example, the ZONELIST command (see The AUI
Command Reference Manual, Volume IV) lists the values of variables.  You can also specify
whether listings are to be sent to your terminal or to a disk file (see the FILELIST command).
When the listings are sent to your terminal, you are prompted by
--More--(  %)
after each screen of the listing.  The number printed before the percent sign represents the
percentage of the file that has been displayed so far.  Responses to this prompt are as
follows:
<return>
Display another line of the listing.
<space bar>
Display another screenful of the listing.
<i><space bar>
Display i more lines.
D or d
Display the next half-screen (a scroll) of the listing.
<i>D or <i>d
Set the number of lines in the scroll to i and display the next scroll.
<i>Z or <i>z
Set the number of lines in each screen to i and display the next screen.
<i>S or <i>s
Skip i lines and print a screenful of lines.
<i>F or <i>f
Skip i screenfuls and print a screenful of lines.
<i>B or <i>b
Skip back i screenfuls and print a screenful of lines.
Q or q
Stop the listing.
=
Print the current line number in the listing.
.
Repeat the last prompt response.
In these responses, <i> represents an optional integer argument, defaulting to 1. If you are
familiar with the UNIX operating system, you will recognize that the above options corre-
spond closely to the options of the 'more' command.

1.8  Units
In model definition no particular unit system is assumed.  Any consistent unit system may be
adopted.  Certain thermodynamic constants do, however, have a choice of temperature unit
system (Celsius/Centigrade/Kelvin, Fahrenheit/Rankine).
1.9  Tips for writing batch files
Increasing execution speed: The AUI contains features that are useful when you enter
commands using the dialog boxes, but are not useful when you read commands from a batch
file.  These features are activated by default.  You can deactivate the features to increase the
speed at which batch files are processed, and to reduce the memory requirements of the AUI.
The features are
Undo/redo storage:
Command CONTROL UNDO=-1 turns off storage for undo/redo information.
Automatic model rebuilding:
Command CONTROL AUTOMREBUILD=NO turns off automatic model rebuilding.
Session file creation:
Command FILESESSION NO  turns off creation of the session file.
Storage of session file information in the database:
To turn off this feature, use the command CONTROL SESSIONSTORAGE=NO.
Stopping after an error or memory overflow is detected:
Command CONTROL ERRORACTION=SKIP  activate a feature that AUI skips the
remaining commands in a batch file after an error or memory overflow is detected.
Summary:
Use the following commands to perform all of the above actions:
FILESESSION NO
CONTROL
UNDO=-1 AUTOMREBUILD=NO SESSIONSTORAGE=NO,
ERRORACTION=SKIP

DATABASE NEW 
Sec. 3.1   Database operations 
 
 
 
ADINA R & D, Inc. 
3-1 
DATABASE NEW   SAVE  PERMFILE  PROMPT 
 
DATABASE NEW creates a new database.  The new database is initially empty.  Before 
creating the new database, you have the option of saving any current internal database to disk.  
This option is controlled by parameters SAVE and PERMFILE. 
 
SAVE 
[UNKNOWN]

DATABASE OPEN creates a new database using the permanent database file specified in this 
command.  Before creating the new database, the current internal database is optionally saved 
to disk. 
 
FILE 
[the last previously specified permanent 
 
database filename] 
The filename of the permanent database file to be opened.  If you do not enter a filename and 
there is no default value, the program will prompt you for the filename. 
 
SAVE 
[UNKNOWN] 
Used only when a database has been modified.   
 YES  
 
 
The current internal database is saved to disk using the filename specified 
by parameter PERMFILE.

DATABASE ATTACH 
Sec. 3.1   Database operations 
 
 
 
ADINA R & D, Inc. 
3-5 
DATABASE ATTACH   FILE 
 
DATABASE ATTACH allows access to the specified file as an AUI database file.  Unlike 
DATABASE OPEN, DATABASE ATTACH does not make a working copy of the database 
file prior to opening it.  Instead you work directly with the specified file as you use the AUI, 
possibly modifying the file's contents. 
 
The advantages of DATABASE ATTACH as compared to DATABASE OPEN are:  disk 
requirements are reduced because the AUI does not create a copy of the database file, and the 
CPU time to attach a database is much less than the CPU time required to open the same file. 
 
The disadvantages of DATABASE ATTACH are:  (1) important information can be 
inadvertently modified or deleted from an attached database file, (2) the attached database 
cannot shrink, but can only grow as the AUI is used and (3) an attached database file cannot 
be saved, but can only be detached using DATABASE DETACH. 
 
Before DATABASE ATTACH can be used, any current database must first be saved, and 
then DATABASE CREATE or DATABASE NEW must be used to create a new database.  
DATABASE ATTACH can be used only if the current database is new and unmodified. 
 
Exiting the AUI when a database is attached causes the database to automatically detach. 
 
FILE 
The filename of the permanent database file to be attached.  If no file name is entered, the 
AUI will prompt you for the filename. 
 
Chap. 3   Input/Output 
DATABASE DETACH 
 
 
 
3-6 
AUI Command Reference Manual: Vol. III − ADINA CFD Model Definition 
DATABASE DETACH   PERMFILE  PROMPT 
 
DATABASE DETACH creates a permanent database file by detaching the working copy of 
the database file.  Unlike DATABASE SAVE, DATABASE DETACH does not create a new 
permanent database file. 
 
The advantages of DATABASE DETACH as compared to DATABASE SAVE are: disk 
requirements are reduced because the AUI does not create a copy of the database file, and the 
CPU time to detach a database is much less than the CPU time required to save it. 
 
The disadvantage of DATABASE DETACH is the AUI does not compress the database file 
by removing unused records. 
 
After the database is detached, the AUI creates a new empty internal database. 
 
A database can be detached at any time whether or not it was attached using DATABASE 
ATTACH. 
 
PERMFILE 
The working copy of the database file is renamed to PERMFILE. 
 
PROMPT 
[UNKNOWN] 
Used when saving a permanent database file. 
 YES 
 
 
You will be prompted "Ready to save permanent database file?".

READ reads AUI input commands from the file specified by parameter FILE until the end of 
the file is reached or the READ END command is encountered in the file.  After the READ 
command is executed, subsequent input is read from the previous command input source (that 
is, the input source from which the READ command was entered). 
 
READ commands can be nested (that is, a file processed by the READ command can itself 
include a READ command). 
 
FILE 
The name of the file from which AUI commands are read (up to 80 characters long).  Note 
that the name END is not allowed. 
 
REWIND 
[NO] 
If the file pointer is at end-of-file or if the file is not currently open, the read file is rewound 
before beginning to read commands regardless of the value of this parameter.  {YES / NO} 
 
SCANDATA 
[' '] 
If SCANDATA is specified, the file is scanned until the SCANDATA string (1 - 80 
characters) is found anywhere within an input record.  Reading of input data from the file 
starts at the beginning of the record that contains the string.

FILESESSION controls the generation and output of a session file.  The session file contains 
the commands needed to repeat an AUI session. 
 
A session file differs from an echo file in that: 
 
1) You can generate a session file from a user-interface AUI session (this is the primary 
use of the session file). 
 
 
2) A session file contains all command parameters, regardless of whether you entered 
them or whether they were default parameters. 
 
 
3) Changes to data input lines are handled in a different manner.

PARAMETER 
 
 
 
3-28 
AUI Command Reference Manual: Vol. III − ADINA CFD Model Definition 
 
All trigonometric functions operate on or return angles in radians. 
 
Examples 
 
PARAMETER  A  '3.0'  
 
 
 
 
// A = 3 
PARAMETER  B  '5 + 7'  
 
 
 
// B = 12 
PARAMETER  C  '6 *  \  
 
 
 
// The string can be entered on several 
      5 '   
 
 
 
 
// command lines as in this example; C = 30 
 
Parameter substitution  
 
 
 
 
 
 
When the command-line parser finds a token value that starts with a $, the parser finds the 
parameter name with that token value and substitutes the parameter value. For example, in 
the commands 
 
PARAMETER  X1  '2.0/3.0' 
PARAMETER  X2  'SQRT(5.0)' 
PARAMETER  X3  'SIN(2.0)' 
BODY  BLOCK  DX1=$X1  DX2=$X2  DX3=$X3 
 
the parser looks for the values of X1, X2 and X3 and substitutes the values (e.g. the characters 
'0.666666666666667') for the names (e.g. the characters 'X1'). Hence the above 
commands are exactly equivalent to the command 
 
BODY  BLOCK  DX1=0.666666666666667  DX2=2.23606797749979, 
      DX3=0.909297426825682 
 
The token values need not be in upper-case: 
 
BODY  BLOCK  DX1=$x1  DX2=$x2  DX3=$x3 
 
Parameter substitution occurs before command execution, so the following is allowed: 
 
PARAMETER  A  '2.0' 
PARAMETER  A  '$A + 1'     
// A = 3 
 
Now you may want to put the symbol $ into a string without parameter substitution occuring. 
The rule is: if the next character after the $ is a letter [a-z], the command-line parser attempts 
parameter substitution. So 
PARAMETER A '3.0' 
USERTEXT ABC 
'The cost is $2000.00' 
'The size is $A' 
DATAEND 
PARAMETER 
Sec. 3.6   Auxiliary commands

is equivalent to 
 
USERTEXT ABC 
'The cost is $2000.00' 
'The size is 3' 
DATAEND 
 
A convenient way to output the value of a single parameter is with the ECHO command: 
 
PARAMETER X1 '2.0/3.0' 
ECHO $X1 
ECHO 'The value of X1 is $X1' 
 
Auxiliary commands 
 
 LIST  PARAMETER 
 
Lists the values of all parameters.

Outputs the given string. This command can be used to output the value of a parameter, 
see the examples given in the PARAMETER command description. STRING is a string 
(up to 256 characters long).

UNDO
[5]
The UNDO parameter controls the number of commands that can be undone using the UNDO
command.  If UNDO = 0, the UNDO command cannot be used, if UNDO = 1, UNDO can be
used to undo the effects of the previous command, if UNDO = 2, UNDO can be used to
undo the effects of the previous two commands, etc.  Setting UNDO = 0 can significantly
speed up the processing of batch files.
PROMPT
[UNKNOWN]
Controls the default behavior for prompts which may arise from various commands.
NO
No command prompts will be issued - this is useful in batch
mode - eliminating any interaction.
YES
Command prompts are always issued.
UNKNOWN
Command prompts are issued only when necessary.
AUTOREPAINT
[YES]
When AUTOREPAINT = YES, the AUI automatically repaints that area of the graphics
window that is exposed to the removal or motion of overlapping windows or dialogs.  You
may want to set AUTOREPAINT to NO to suppress the repainting; in that case, you can use
the REFRESH command whenever you want to repaint the graphics window.
DRAWMATTACH
[YES]
When DRAWMATTACH = YES, mesh plot attachments (band plots, load plots, element
vector plots, reaction plots, line contour plots) are drawn.  Otherwise, they are not drawn.
CONTROL
4-4
AUI Command Reference Manual: Vol. III  ADINA CFD Model Definition
Chap. 4  Interface control and editing
One use of this option would be to turn off drawing of mesh plot attachments before moving
the mesh plots with the mouse.
DRAWTEXT
[EXACT]
DRAWLINES
[EXACT]
DRAWFILLS
[EXACT]
These options control the drawing of text, lines and fills:
EXACT
Use the requested colors while drawing.
SATURATED
Convert all colors to saturated colors before drawing.
GRAY
Convert all colors to gray scales before drawing.
INVERSE
Convert all colors to the INVERSE color before drawing (the
INVERSE color is the opposite of the background color).
NO
Do not draw.
AUTOMREBUILD
[YES]
When you enter a command that alters the geometry or finite element model, the AUI rebuilds
all corresponding data structures so that the model can be re-plotted.  This feature can be
deactivated by setting AUTOMREBUILD = NO (in this case, if you want to plot the model,
you must use the ADINA, ADINA-T or ADINA-F commands to rebuild the model before-
hand).
Setting AUTOMREBUILD = NO can significantly speed up the processing of batch files.
Notes :
1) One important use of parameters DRAWTEXT, DRAWLINES, DRAWFILLS
is when making plots in black and white for reports.  In this case you might
use DRAWTEXT = INVERSE, DRAWLINES = INVERSE, DRAWFILLS =
GRAY.
2) The drawing parameters apply both to graphics as displayed on the screen
and to graphics as produced using SNAPSHOT or MOVIESAVE.
3) One use of DRAWFILLS = SATURATED is to speed up shaded color image
drawing, especially using X Window graphics; all shades of each color are
converted to the same color, resulting in significantly fewer color changes.
ZONECOPY
[NO]
Controls whether the commands BANDPLOT, MESHPLOT, ELINEPLOT, EVECTORPLOT,
LCPLOT, REACTIONPLOT, BANDSTYLE, MESHSTYLE, ELINESTYLE, EVECTORSTYLE,
LCSTYLE, REACTIONSTYLE create copies of the input zones. Zone copies are always
created by these commands in AUI 7.0 but not in later versions of the AUI. The preferred
CONTROL

CONTROL
setting of ZONECOPY is NO, but YES may be necessary to read input/session files produced
for/by AUI 7.0. {YES/NO}
SWEEPCOINCIDE
[YES]
Controls whether the SURFACE/VOLUME REVOLVED/EXTRUDED geometry definition
commands check for coincident lines and surfaces, as well as for coincident vertices (points).
AUI 7.0 did not attempt to connect adjacent surfaces/volumes, resulting in duplicate lines
and surfaces fro such sweep geometry definition. The default in AUI 7.1 and higher is to
connect adjacent surfaces/volumes whenever possible. However, AUI 7.0 input/session files
which contain such sweep geometry will likely fail, so it may well be necessary to set
SWEEPCOINCIDE=NO to correctly process older input files. {YES/NO}
SESSIONSTORAGE
[YES]
If SESSIONSTORAGE = YES, the subsequent commands are stored in the AUI database. You
can output these commands using the command COMMANDFILE. In the event of a system
crash, you can retrieve these commands by opening the AUI temporary database, and
subsequently issuing the COMMANDFILE command.
If SESSIONSTORAGE = NO, subsequent commands are not stored in the AUI database and
therefore cannot be retrieved. You may wish to set SESSIONSTORAGE = NO before reading
commands from a batch file to eliminate the overhead of storing those commands within the
AUI database.
Note that the storage of commands in the AUI database is independent of the writing of
commands to the session file determined by command FILESESSION.
DYNAMICTRANSFORM
[YES]
Controls how the program indicates the transformation when you move, resize or rotate
graphics using the mouse.  If DYNAMICTRANSFORM=YES, the program redraws all picked
graphics completely and redraws all other graphics that overlap the picked graphics.  If
DYNAMICTRANSFORM=PARTIAL, the program partially redraws all picked graphics and
does not redraw overlapping graphics.  If DYNAMICTRANSFORM=NO, the program
indicates the transformation using a bounding box.
UPDATETHICKNESS
[YES]
When you change the thickness of geometry surfaces or faces, all elements generated onto
the surfaces or faces are automatically updated with the updated thickness. {YES/NO}
In AUI 7.2 and lower, elements are not automatically updated.  Therefore you may need to set
UPDATETHICKNESS=NO so that input files constructed for use with AUI 7.2 and lower work
correctly.

AUTOREGENERATE
[NO]
If AUTOREGENERATE=YES, the program regenerates the graphics after you run a command
that changes the model definition.  This parameter only applies to commands that are run
from the command-line (or read from a file); it does not apply to dialog box input from the user
interface.  Note that the user interface always regenerates the graphics after you use a dialog
box that changes the model definition. {YES/NO}
ERRORACTION
[CONTINUE]
Defines AUI action when error is detected. Parameter affects only commands read from a
batch file.
CONTINUE
AUI continues to process commands.
SKIP
AUI skips the remaining commands up to the next READ END
command, if any.
