Hi Nimasam
did you find a way to calculate drag in interFoam? i was looking at "forces" tool to calculate pressure and viscous forces over a patch using interFoam but i am not sure it works for multiphase (see my post here http://www.cfd-online.com/Forums/ope...mulations.html). What do you think about that?

regards

andrea
