First of all, thanks for the softtware, and all the information given in the forum. It really helped me a lot, starting with Elmer.
Now on to my "problems" :
I am trying to simulate the transient heating of a material with a phase change. I was able to setup a model and a simulation which comes close to the practical tests i have done this far.
Now i want to implement the phase change. I already read a lot of topics dealing with several things about phase change and writing UDF.
Some things are still unclear to me:
1) what exactly does "Phase change interval (2,1) = T1 T2" mean? perhaps this could already solve my issues.
2) is it possible to write a UDF with a variable that switches on a specified temperature of the model (i want to create a UDF/model that implements subcooling, for example: the PCM melts at 300K and freezes back again at 270 K ). If there already is a model, i would be happy to know

I can attach my current files, if someone could take a look.
Thanks in advance!
