Description

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

Usage

1. Click on or choose Model → Mechanical Constraints → Constraint fixed from the top menu.
2. Select in the 3D-view the object the constraint should be applied to, which can be
   1. vertices (corners)
   2. edges
   3. faces

Limitations

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