Heat Source (Fracture)
Use this subnode to add an internal heat source Qfr within the fracture. Add one or more heat sources. If this subnode is applied on a pair, note that the source term is applied on the source side.
Heat Source
Select the General source (the default) or Heat rate button to define Qfr.
•
For General source enter a value or expression for Qfr as a heat source per volume.
•
For Heat rate define the heat rate Pfr. In this case Qfr = Pfr ⁄ V where V = Adfr with A equal to the area of the boundary selection.
You can specify the source to be a harmonic perturbation in a frequency domain analysis. To mark the source as being a harmonic perturbation, right-click the node and choose Harmonic Perturbation. Note that this updates the node’s icon. See Theory for Harmonic Heat Transfer for more details.
