Re: Transient Phase Change Solver

Post by raback »

Hi Roland,

The only major thing I did was enable the heat solver to be solved both in steady state + transient within same simulation. So this conflicting looking thing in the sif:

Code: Select all

  Before Simulation = True
  Exec Solver = Always
This makes the initial guess smooth and it is good to start from it.

Additionally, for feedback I added the variable "pull velocity" that can be used to pull the crystal. But it was not used in the files I sent.

Nothing else was changed for this case.

Hello Peter,
Ok for that. As said before I will install the latest release and run your model with the prompt commands but also with the GUI (since you said that it must also work with the GUI).
Just one additionnal thing: as we need to add the phase change heat release as a heat transfer BC on the phase change interface, which depends on the Stefan phase change velocity, have you an idea of how we could get this velocity as a variable from the Transient Phase Change solver?
