Description

Creates a FEM constraint for contact between 2 surfaces.

How to use

  1. Click on or choose ModelMechanical Constraints Constraint contact from the top menu.
  2. Select the master face.
  3. Select the slave face.
  4. Enter a contact stiffness.
  5. Enter a friction coefficient.

Limitations

  1. The contact constraint can only be applied to two faces.
