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