Hi, Dear researchers!
I am considering modeling the Si crystallization using matlab code. The capillary effect will also be considered.
I found there is general difference in phase field and level set method. In the following paper, both of them can work well. But just not sure how these two methods works with the capillary effect.
Thanks!
Conference Paper Phase-Field Versus Level Set Method for 2D Dendritic Growth
in any case you will need something describing at least three-phase equilibria and triple junctions to account for wetting phenomena (Youngs law, Herring Torque terms). I know that there are approaches for this in multi-phase-field modelling. For level set (e.g phase fraction 0.5 between two phases) I would not know how to set the level at the triple junction where the three phases meet (1/3 ?...but how to switch to 0.5 at the directly adjacent dual interface then.?.)
Hope this helps...
Yours
George
I do not know about level set, but according to my experience phase field method can handle capillaries in a intuitive way.
Sorry for getting back to you two late. I was doing some side simulations. After your comments, I read some papers. I found level set is more complex in the surface tension modeling (Thanks Henrique). Also, literature indicates that the phase field could be used to simulate the droplet spreading, therefore the three-phase contact line could be solved. (Thanks George!) I will give phase field a vote.
Thank you again.

@Letian,
Hello,
I know the question is quite old but can you suggest some text comparing Level set and phase-field method ( of course showing advantage of latter as described by you)
Thanks
