Description
Creates a FEM constraint for a prescribed displacement of a selected object for a specified degree of freedom.
Usage
- There are several ways to invoke the command:
- Press the
FEM ConstraintDisplacement button.
- Select the Model → Mechanical Constraints →
Constraint displacement option from the menu.
- Press the
- In the 3D view select the object the constraint should be applied to, which can be a vertex (corner), edge, or face.
- Choose a degree of freedom or prescribe a displacement.
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
