There are many different approaches. Which have to be programmed manually, and nobody wants to do it. For Microstructures containing some grains Multiphase field approaches are the favourites. (not in comsol). Dendritic growth simulation need thermodynmaics coupling containing a lot of data.
If you want to implement it, please tell me.
Kind Regards
Hello,
1. Now I am simulating dendritic solidification of pure materials by comsol PDE mode. I downloaded a ppt from the comsol official website, in this ppt an example called "phase field modeling of solidification" was given. I followed the author's steps but failed to solve the model correctly (an error occurred). In this ppt, the author didn't give out the geometry, initial and boundary conditions. I know for the phase field method, some parameters must be chose carefully.
2. Are you familiar with or have you ever done the simulation of dendritic solidification ? I know in literatures many author programmed manually using finite difference method, do you have such kind of programs that I can refer to?
Thank you!
