* 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.
{{VersionMinus|0.20}}: The body heat source is applied to the whole model, meaning all bodies of the setup. It is not possible to select an individual body.

Description

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

Usage

  1. Either press the FEM_ConstraintBodyHeatSource or select the menu Model → Thermal Constraints → Constraint body heat source.
  2. Set the value:
    • version 1.0 and above: For a 3D analysis, select a 'solid' (body) from your model, for a 2D analysis select a face.
    • version 0.20 and below: Since the constraint has no task dialog, use the property editor and set the property DataHeat Source.

Limitation

version 0.20 and below: The body heat source is applied to the whole model, meaning all bodies of the setup. It is not possible to select an individual body.
