Descriere

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

Cum se folosește

1. Click pe sau alegeți Model → Mechanical Constraints → Constraint displacement din meniul de sus.
2. Selectați în vizualizarea 3D obiectul la care trebuie aplicată constrângerea, care poate fi
   1. vertices (corners)
   2. edges
   3. faces
3. Alegeți un grad de libertate pentru a stabili sau a prescrie o deplasare la.

Note

1. constrângerea utilizează tabelul *BOUNDARY în CalculiX. Fixarea unui grad de libertate este explicată la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node164.html și se precizează o deplasare pentru un anumit grad de libertate http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node165.html
