Dear Foamers,

I have a question regarding the reference class for calculating the phase transition solidificationMeltingSource

I've read the source code, but I still don't understand how the heat capacity determination works. Is it possible to enter the heat capacity corresponding to the solid phase? Is the CpRef parameter responsible for this?

Code:
      Property  | Description                       | Type   | Reqd | Dflt
      type      | Type name: solidificationMeltingSource  | word   | yes   | -
      Tmelt     | Melting temperature [K]           | scalar | yes  | -
      L         | Latent heat of fusion [J/kg]      | scalar | yes  | -
      thermoMode  | Thermo mode                     | word   | yes  | -
      rhoRef    | Reference (solid) density         | scalar | yes  | -
      beta      | Thermal expansion coefficient [1/K] | scalar | yes | -
      relax     | Relaxation factor [0-1]           | scakar | no   | 0.9
      T         | Name of operand temperature field | word   | no   | T
      rho       | Name of operand density field     | word   | no   | rho
      U         | Name of operand velocity field    | word   | no   | U
      phi       | Name of operand flux field        | word   | no   | phi

      q         | Coefficient used in porosity calc | scalar | no   | 1e-2
      Cp        | Name of specific heat capacity field | word | cndtnl | Cp
      CpRef     | Specific heat capacity value      | scalar | cndtnl  | -
Thank you in advance
