Interface location problem in interFoam
 

Hello,
I am simulating capillary flow using interfoam. I am facing a strange problem. My domain size is very big. So I cannot use very big meshes. I see that if the mesh is very coarse, the interface travels faster than that for finer meshes. Is this kind of behavior expected in interfoam? Does anyone know how can we resolve this issue?

you should make it fine enough that result gets independent of mesh! ( means when you make it finer the results have a bit change not a big difference)
