Re: simulation of solidification or crystallization using Phase-field method?


Hi

I know this paper. I did try this in my first time too,

Now I am implementing newer versions of phasefields. You need 2 PDE and 1 heat transfer to solve

(phi, c,T)

If you have a running file please tell me. My simulation is not running up to now.

Kind regards


Hi, Daniel, thanks for your reply!
You mean you tried the model in the paper, and it also cannnot work ? So what's the problem of your model? my model's error are:
----------
Undefined value found.
- Detail: Undefined value found in the stiffness matrix.
There are 40296 equations giving NaN/Inf in the matrix rows for the variable mod1.theta
at coordinates: (0.5,-0.5), (0.495,-0.5), (0.49,-0.5), (0.485,-0.5), (0.48,-0.5), ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns
----------
it seems that something is wrong at the boundary (the coordinates are on one of the boundaries).
Now you are doing new version of phase field, it is more complex, which literatures are you referring to? Good luck to both of us!
