Description

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

Usage

  1. Press the FEM ConstraintDisplacement.svg button or choose Model → Mechanical Constraints → FEM ConstraintDisplacement.svg Constraint displacement‏‎ from the top 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.

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
