Problem of smearing vof air-liquid
 
I have a problem with the following simulation. I have two cylinder that round with the same tangencial speed. There is a gap of 1 [mm] between the two cylinder and the second is complety immersed in liquid. The first cylinder is immersed for few mm and put the fluid in vertical position. The problem is that I see for the cylinder immersed a smeraing of fluid during rotating. The dimension of cell is 0.6 [mm] I considered surface tension, gravity, k-epsilon model, 10 iteration every time step, and time step I set of 1e-04 [s].
I accept some conseil to resolve these problem than you very much
