Creates a FEM constraint for a fixed geometry entry by locking all 6 degrees of freedom of the selected object.


  1. There are several ways to invoke the command:
    • Press the FEM ConstraintFixed.svg FEM ConstraintFixed button.
    • Select the Model → Mechanical Constraints → FEM ConstraintFixed.svg Constraint fixed 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.


You cannot mix object-types within the same constraint. Use one fixed constraint for each object type.
