Thickness
Use this node with 2D components to model domains with another thickness than the overall thickness that is specified in the Heat Transfer interface Physical Model section. In 2D geometries, the temperature is assumed to be constant in the out-of-plane direction (z direction with default spatial coordinate names). The heat equation is modified to take that into account. See Equation 4-176 and Equation 4-177.
Thickness
Specify a value for the Thickness dz of the domain in the out-of-plane direction. This value replaces the overall thickness in the domains that are selected in the Domain Selection section, and is used to multiply some terms into the heat equation.
The Thickness feature is disabled when at least one of the multiphysics couplings (Heat Transfer with Surface-to-Surface Radiation, Heat Transfer with Radiation in Participating Media, Heat Transfer with Radiative Beam in Absorbing Media) is active while solving on the same domain. This is noticed through a warning node displayed under Compile Equations. The radiation interfaces assume an infinite medium in the out-of-plane direction, they are thus not compatible with these features.
