Description

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

Usage

  1. Click on FEM ConstraintDisplacement.png or choose ModelMechanical ConstraintsFEM ConstraintDisplacement.png 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
