Thin Layer

This node defines the thickness and thermal conductivity of a resistive material located on boundaries. This material can be formed of one or more layers.

Pair Selection

If this node is selected from the Pairs menu, choose the pair on which to apply this condition. A pair has to be created first. See Identity and Contact Pairs in the COMSOL Multiphysics Reference Manual for more details.

Thin Layer

The only options for Layer type is Resistive.

From the Specify list select Layer properties (the default) or Thermal resistance.

•	For Layer properties enter a value or expression for the Layer thickness ds.

•	For Thermal resistance enter a value or expression for the Thermal resistance Rs.

Heat Conduction

The default Layer thermal conductivity ks is taken From material. For User defined select Isotropic, Diagonal, Symmetric, or Anisotropic to enter another value or expression.
