## Description

Creates a FEM constraint for a temperature boundary condition.

## Usage

- Click on or choose Model →
**Thermal Constraints**→ Constraint temperature from the top menu. - Select in the 3D-view the object(s) the constraint should be applied to, which can be:
- vertices (corners)
- edges
- faces

- Enter a temperature to apply to the object.

## Limitations

## Notes

- 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
