Requests contain standard displacement, velocity, acceleration, or force information that can help you
investigate the results of simulations. You can also define other quantities (such as pressure, work,
energy, momentum, and more) that you want output during a simulation.
Adams stores the requests in request files (.req).
Setting Request Activity
By default, requests for each element type are active. You can, however, deactivate requests for a certain
element type. Any activity changes will only be retained during the current session.
Note that for the bushing element, the activity switch is saved in the subsystem/assembly file.
To set request activity:
1. From the Standard Interface's Tools menu, select Request Activity.
2. Press F1 and then follow the instructions in the dialog box help for Toggle Request Activity.
3. Select OK.
Storing Request Activity
To store the request activity, you should group activity using parameter variables, which are stored in
To store request activity in Template Builder:
1. Create a parameter variable to store the activity of the request as a 1 for active, 0 for inactive.
For example, pvs_request_activity.
2. Create a group with command language:
Tools -> Command Navigator, group -> create
3. Add your requests to the group.
4. For the expr_active parameter of the group (1 = active, 0 = inactive), create a function that uses
the parameter variable in step 1.
The commands might look as follows:
group create &
group_name = ._my_template.my_request_activity
objects_in_group = ._my_template.request0, &
expr_active = (pvs_request_activity)
For more examples, investigate templates in the shared database that have the group
kinematic_mode_active, which is used for the Kinematic Mode option.
