Creates a FEM constraint for a prescribed displacement of a selected object for a specified degree of freedom.


  1. There are several ways to invoke the command:
    • Press the FEM ConstraintDisplacement.svg FEM ConstraintDisplacement button.
    • Select the Model → Mechanical Constraints → FEM ConstraintDisplacement.svg Constraint displacement option from the menu.
  2. In the 3D view select the object the constraint should be applied to, which can be a vertex (corner), edge, or face.
  3. Choose a degree of freedom or prescribe a displacement.
