Description
Defines an internally generated body heat given in W/kg (not J/m³).
Usage
- There are several ways to invoke the command:
- Press the FEM ConstraintBodyHeatSource button.
- Select the Model → Thermal Constraints → Constraint temperature option from the menu.
- In the 3D view select the objects the constraint should be applied to, which can be a vertices (corners), edges, or faces.
- Enter a specific heat value to apply to the objects.
