Description

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

Usage

  1. Press the Body heat source button or select the menu Model → Thermal boundary conditions and loads → Body heat source.
  2. Set the value:
    • version 0.21 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 tool 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.
