Heat Source (Thin Film)

Use this subnode to add an internal heat source Qf within the thin film. 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 (the default) or button to define Qf.

•

For enter a value or expression for Qf as a heat source per volume.

•

For define the heat rate Pf. In this case Qf = Pf ⁄ V where V = Adf 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.
