Temperature (Thin Layer, Thin Film, Fracture, and Heat Transfer in Shells)

Use this subnode to specify the temperature on a set of lines (geometrical edges in 3D or geometrical points in 2D and 2D axisymmetric) that represent the boundaries of a thin domain (layer, film, fracture, or shell). Only edges (3D) or points (2D and 2D axisymmetric) adjacent to the boundaries can be selected in the parent node.

Edge Selection

Select the edges on which to specify the temperature. The check box makes the node applicable only if a layered material is defined on the edge. If a layered material ( with specified, , , or ) is available, its name is then displayed beside the edge index (for example, slmat1), otherwise the edge is marked as not applicable.

Note that when the is in the section of the parent interface or node, the check box is not editable.

In addition, in 2D, edges are modeled as points and this section is named , containing a check box.


	The desired selection for the node may correspond to boundaries with different layered materials. See Layered Material, Layered Material Link, Layered Material Stack, Layered Material Link (Subnode), and Single-Layer Materials in the COMSOL Multiphysics Reference Manual.

Shell Properties

This section is available only when the is in the section of the parent interface or node. You can limit the contribution to individually selected layers by clearing the check box. For a given or , you get access to a list of check boxes for the selection of the individual layers.

Temperature

For , enter a value or expression for the T0. Else, select an defined in an node under .

The equation for this condition is T = T0 where T0 is the prescribed temperature.

	You can specify a harmonic variation of the temperature value in a frequency domain analysis of perturbation type, by adding a Harmonic Perturbation subnode. See Theory for Harmonic Heat Transfer for more details.
