The Bioheat Transfer (ht) interface (), selected under the Heat Transfer branch () when adding a physics interface, is used to model heat transfer by conduction, convection, and radiation. A Biological Tissue model is active by default on all domains. All functionality for including other domain types, such as a solid domain, are also available.

When this version of the physics interface is added, these default nodes are added to the Model Builder: Biological Tissue (with a default Bioheat node), Thermal Insulation (the default boundary condition), and Initial Values. All functionality to include both solid and fluid domains are also available. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions and sources. You can also right-click Bioheat Transfer to select physics features from the context menu.
