Descriere

Creează o constrângere MEF pentru a prescrie deplasarea unui obiect selectat pentru un număr specificat de grade de libertate.

Cum se folosește

  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.

Limite

Note

  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
