Description
Creates a FEM constraint for a prescribed displacement of a selected object for a specified degree of freedom.
Usage
- Click on or choose Model → Mechanical Constraints → Constraint displacement from the top menu.
- Select in the 3D view the object the constraint should be applied to, which can be
- vertices (corners)
- edges
- faces
- Choose a degree of freedom to fix or prescribe a displacement to.
Limitations
Notes
- 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
