Description

Crée une contrainte FEM pour une condition de limite de température.

Utilisation

1. Cliquez sur or choose Model → Thermal Constraints → Constraint temperature dans le menu principal.
2. Sélectionnez dans la vue 3D l'objet auquel la contrainte doit être appliquée, qui peut être
   1. sommets (coins)
   2. bords
   3. faces
3. Entrez une température à appliquer à l'objet.

Notes

1. La contrainte utilise la carte *BOUNDARY dans CalculiX. La contrainte temperature est expliquée à http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node163.html
