Brick Model Example: brick1.ifu
In this example we will use Mesh/PRO to create a brick model in FE/Pipe. The model
will consist of a simple bar, 12”x2”x2”. Thermal boundary conditions, pressure and fixity
boundary conditions will be applied. This example will also give an example of using
StresPLOT to post-process stress results.
The general steps are as follows:
1. Generate Brick Elements.
2. Apply boundary conditions to surface meshes.
3. Export model to FE/Pipe.
4. Post-process stresses using StresPLOT.
1. Generate Brick Elements
There are two basic ways to generate brick elements with Mesh/PRO. One is to create a
surface and then extrude the surface. The second is to create two surfaces and then
generate brick elements between them. To get started start AutoCAD and then start
In the Mesh/PRO main screen select the “3-D Brick Model”. Next we need to
synchronize Mesh/PRO to the current drawing. Select File and click “Sync MeshPRO to
current drawing”. A message should appear confirming the sync was successful. Finally,
under the “Brick” menu click “PRG Brick Mesher” to bring up the Brick Meshing menu
to use with AutoCAD.
In the AutoCAD drawing, we will draw a base surface for our brick model. To do this,
create a layer simply named “1”. As in the Axisymetric model, this will tell Mesh/PRO
that the elements generated with this layer will correspond to Material ID # 1 in FE/Pipe.
Using layer “1”, we lay out a base surface with the 3D Face command. This is the most
convenient way to create a surface, however it is limited to straight edges only. If there
are curved edges, the Edge Surf command must be used instead. In this case, we use the
