Beschreibung

Creates a FEM constraint for a temperature boundary condition.

Anwendung

1. There are several ways to invoke the command:
   • Press the FEM ConstraintTemperature button.
   • Select the Model → Thermal Constraints → Constraint temperature option from the menu.
2. In the 3D view select the objects the constraint should be applied to, which can be a vertices (corners), edges, or faces.
3. Enter a temperature to apply to the objects.

Hinweise

1. The temperature constraint uses the *BOUNDARY card in CalculiX. the temperature constraint is explained at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node163.html
