Another question what is the velocity-pressure algorithm that you use? Do you under-relax the pressure? Can you display the isocontour 0.5 of the Fs field? It should coincides with the position...

It is clear on this figure that the interface is not well captured. In fact I don't understand well what you are doing when you say that you handle one-phase problem and getting velocity...

Hi Vivien, Visibly the problem comes from a bad mass conservation. So if your code performs well in the monophasic case, you have to search around two points: 1) is the way the volume fraction...

First check if your Navier-Stokes solver performs well in monophasic case (same rho, same mu). Then for large density and/or viscosity ratios instead of using arithmetic mean as you did, use rather...
