The default option for the Thermal Contact node is Solid, which specifies that the heat source Qb is defined in the material frame. Because the heat transfer variables and equations are defined in the spatial frame, the inputs are internally converted to the spatial frame. See Conversion Between Material and Spatial Frames for details.

The From material option uses the option selected in the Material type list of the Material Properties section of the material applied on the boundary on which the node is active.

For Weighted harmonic mean, enter values or expressions for the Young’s modulus, upside, Eu, the Young’s modulus, downside, Ed, the Poisson’s ratio, upside, νu, and the Poisson’s ratio, downside, νd. If this node is selected from the Pairs menu, enter instead values or expressions for the Young’s modulus, source, Esrc, the Young’s modulus, destination, Edst, the Poisson’s ratio, source, νsrc, and the Poisson’s ratio, destination, νdst.

Upside and downside settings can be visualized by plotting the global normal vector (nx, ny, nz), that always points from downside to upside. Note that the normal vector (ht.nx, ht.ny, ht.nz) may be oriented differently.
In addition, surface plots for the temperatures on the upside (ht.Tu) and downside (ht.Td) of the slit are automatically generated in 3D components.
