Heat Source (Heat Transfer in Shells Interface)
This node describes heat generation within the shell through a dsQ contribution to the right-hand side of Equation 4-72. If it is applied on a pair, note that the source term is applied on the source side.
Express heating and cooling with positive and negative values, respectively. Add one or more nodes as needed; all heat sources within a boundary contribute to the total heat source. Specify the heat source as the heat per volume in the domain, as a linear heat source, or as a heat rate.
Boundary Selection
Select the boundaries on which to apply the heat source. The Restrict to layered boundaries check box makes the node applicable only if a layered material is defined on the boundary. It is editable when the Shell type is Layered shell in the Shells Properties section of the parent interface.
Shell Properties
Different settings are available, depending on the settings in the Shell Properties section of the parent interface:
When the Shell type is Layered shell in the Shells Properties section of the parent interface, the same layered material is used in the Heat Source node, but you can limit the contribution to individually selected layers by clearing the Use all layers check box. For a given Layered Material Link or Layered Material Stack, you get access to a list of check boxes for the selection of the individual layers.
When the Shell type is Nonlayered shell in the Shells Properties section of the parent interface, the Thickness is taken From physics interface in the Heat Source node. You can change to User defined and override the interface setting with a specific value or expression for Lth.
You can visualize the selected layered materials and layers in each layered material by clicking the Layer Cross Section Preview and Layer 3D Preview buttons.
Material Type
These settings are the same as for the Heat Source node available for the other interfaces.
Heat Source
These settings are the same as for the Heat Source node available for the other interfaces.
In 2D components the heat source is multiplied by dz to take into account the out-of-plane thickness.
