Hey guys,

I would like to simulate the melting behavior of RTHC35. Its a paraffin, but has no eutectic melting point but some kind of a melting range between 27 C and 42 C (attached picture).

I tried to simulate the problem by using a solidus temperature of 34 and liquidus of 36 C with the summed up latent enthalpy of approx. 240000 J/kg, but this doesnt give proper results.

Any ideas how to improve this model? I would need some kind of temperature depend latent heat values...
