The Heat Transfer with Phase Transformations multiphysics interface combines the Metal Phase Transformation interface with the Heat Transfer in Solids interface. Phase transformations are generally temperature dependent, and this interface is a suitable starting point for modeling metallurgical phase transformations that occur during a thermal transient. Latent heat is generated during phase transformations, and the interface transfers this generated heat to the heat equation that is used by the Heat Transfer in Solids interface, as shown in Figure 2-3. This is done using the Phase Transformation Latent Heat multiphysics coupling.
