very simple problem with interFoam
 

dear foamer
I have very simple problem with interFoam:
I wanna saw the surface tension true implemented in interFoam. I used a square without gravity and I must saw square change into circle and steady. I run my case after that square change to circle but droplet start move in domain and has a unsteady regime and stream line is wrong. I change boundary conditions and mesh. answer be better but still answer is wrong and just amplitude move is decrease.
I'm used openFoam 2.2.1 and ubuntu 12.04
do you have any idea about my problem?
best regards
Sajad
