==Limitations==
* This constraint works only with the Elmer solver, it has no effect when CalculiX is used as a solver.
* Body heat source is applied to the whole model, it's not possible to select individual regions.

Description

Defines an internally generated body heat given in W/kg.

Usage

  1. There are several ways to invoke the command:
    • Press the FEM ConstraintBodyHeatSource button.
    • Select the Model → Thermal Constraints → Constraint body heat source option from the menu.
  2. Since the constraint does not yet has a task dialog, use the property editor to set
    DataHeat Source.

Limitations

  • This constraint works only with the Elmer solver, it has no effect when CalculiX is used as a solver.
  • Body heat source is applied to the whole model, it's not possible to select individual regions.
