About the calculation of "curvature" in "Phase field" and "Level set"

When I see the instructions about the Phase field method and Level set method in Users's Guide, it said that the interface curvature is mean curvature, why mean curvature? If I need is local curvature, what should I do?

Hello I have the same dilema to calculate the curvature. Have you found and answer?. Well I actually use this definition: 2*(1+phipf)*(1-phipf)*tpf.G/tpf.sigma in the Phase field model. But I don't know how to use it as punctual evaluation over a complicated surface. I really pleasure if you know more of me about curvature evaluation that would you mind shearing.

Hi ,

Where can I find level set in COMSOL . I currently have version 4.2 .


Best,
