So it's fully encapsulated. You can use a phase exchange model to move from one solid phase to another, use the material properties to account for melting energy. Or you can use a single granular phase and alter the specific heat capacity to mimic the phase change enthalpy. 

Have a look at the phase interaction models and for the latter, DEFINE_SPECIFIC_HEAT in the UDF manual (search in Help).Â
