Information

This example checks the implementation of functions that evaluate the temperature- and concentration-dependent thermophysical properties of the medium.

Thermophysical properties (density, specific heat capacity, thermal conductivity and dynamic viscosity) are shown as 0 if the temperature is below the fusion temperature.
