drag calculation
 
hi friends
i simulate bubble rising in openFoam with interFoam how can i calculate drag coefficient in post proccessing ?

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

Hi Nima
