The Heat Transfer in Building Materials Interface
The Heat Transfer in Building Materials interface () is automatically added when the Building Materials version of the predefined multiphysics interface Heat and Moisture Transport is added. A Building Material model is active by default on all domains.
Use this interface to model heat transfer in building materials defined as porous media containing moisture, which is a mixture of liquid water and vapor. The temperature equation corresponds to the diffusion equation in which effective thermodynamic properties account for both the dry solid matrix and moisture properties. The latent heat of evaporation is included to define a heat source or sink.
When this physics interface is added, the following default nodes are added in the Model Builder: Building Material, Thermal Insulation, and Initial Values. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions. You can also right-click Heat Transfer in Building Materials to select physics features from the context menu.
