Volume of Fluid Method: how to include capillary forces/surface forces?

chaiitu2896 · July 2, 2015, 10:26

Hi everyone

My project requires me to use volume of fluid method. I studied damBreak case from tutorials but they didn't involve capillary forces/surface forces. does any one know how to include these forces

Try using multiphase solver in foamextend. It seems they have a better volume of fluid method. This is if you are using interFoam solver.

FoamExtend is an extension of OpenFOAM, which is not maintained by ESI group. You can google it.

thanks for the reply but inter Foam already included the surface forces.

@Ashwini Do you know how to install openFoam_extend in windows

Windows, you have to google it. Mostly, it would not be there. Why not linux, it would give you more options, like GERRIS, another opensource package preferred for multiphase flows.
