Benefits of the Different Heat Transfer Interfaces

The benefit of the different versions of the Heat Transfer interface, with ht as the common default name (see Heat Transfer Variables), is that it is easy to add the default settings when selecting the physics interface. At any time, add a or node from the toolbar — the functionality is always available.


	Depending on the available COMSOL products, physics interface options are also available from a Heat Transfer interface by selecting a specific check box under the Physical Model section (for surface-to-surface radiation, biological tissue, radiation in participating media, porous media, or isothermal domain). See Table 5-2 and Table 5-4 for a description of the interface options.

Table 5-2: The Heat Transfer (Ht) Interface Options
Icon	Name	Default Physical model
	Heat Transfer in Solids	No check box is selected.
	Heat Transfer in Fluids	No check box is selected.
	Heat Transfer with Surface-to-Surface Radiation (under the Radiation branch)	The Surface-to-surface radiation check box is selected (which enables the Radiation Settings section).
	Heat Transfer with Radiation in Participating Media (under the Radiation branch)	The Radiation in participating media check box is selected (which enables the Participating Media Settings section).
	Bioheat Transfer	The Heat transfer in biological tissue check box is selected (which enables the Damage Integral Analysis Discretization section).
	Heat Transfer in Porous Media	The Heat Transfer in Porous Media check box is selected (which enables the Porous matrix model list).
	Heat Transfer in Building Materials	The Heat Transfer in Porous Media check box is selected (which enables the Porous matrix model list).
	Heat Transfer	No check box is selected.
