Constraint Constraint-Specific Information
Frictionless Apply a frictionless constraint to a flat or cylindrical surface in
Constraint the part. Frictionless constraints prevent the surface from
moving or deforming in the normal direction relative to the
surface.
To add a constraint:
1 Click the constraint command corresponding with the type of constraint
you want to assign.
2 The select command is active and you can begin selecting the geometry
related to the constraint type. You can expand the dialog box to access
advanced settings.
If you right-click a constraint in the browser, you can: :
Edit the constraint. The appropriate dialog box displays so that you can
make changes.
View reaction forces. Values are zero until a simulation is run.
Suppress the constraint.
Copy and Paste between simulations within the same document.
Delete the constraint.
To rename an item in the browser, click it, pause, click it a second time, enter
a new name, and then press ENTER.
NOTE For some types of simulations you define, constraints are not required.
