Hi!
I tryed to model the behaviour of a phase change material under changing temperatures. I used a enthalpy method to do this. I have Information about the enthalpy at certain temperatures out of a DSC-measurement. These are different for Melting and freezing. Everything is working as Long as i do complete melting and freezing cycles. I just say comsol if gradT is positive use the "heating curve" and if gradT negative use freezing curve.
But i dont know how i can model a incomplete cycle with comsol. I want comsol to do something like:
Change from melting curve to freezing curve, if temperature decreases again, while melting is not completed. This should not happen by a jump but a linear function on the same enthalpy Level betweent the both curves.
If you have some hints or advices for me i would be very happy
