Hello Foamers!

Does anybody know the relationship between interface compression and mesh size to keep the interface sharp?
I.e. when I am using interface compression and a coarse mesh, do I get a sharp interface?

Cheers in advance

I don't think you can improve the interface on a coarse mesh with increased interface compression.

If you need a coarse mesh and a fine interface you can try to use interDyMFoam.
