Description

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

Use

  1. Click on or choose ModelMechanical Constraints Constraint displacement 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
  3. Choose a degree of freedom to fix or prescribe a displacement to.

Limitations

Notes

  1. The constraint uses the *BOUNDARY card in CalculiX. Fixing a degree of freedom is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node164.html and prescribing a displacement for a degree of freedom is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node165.html
