Actually I can only guess what your problem might be, based on the given information. How high is your interface level from the setFieldsDict. In some stability calculations with surface waves I...

I agree with you that the boundary condition wich was fine for p (OF-1.6) is probably wrong for p_rgh (OF-1.7.1). I have attached some different variations in the boundary conditions for p_rgh,...

I just had implemented Neumann boundary conditions (zeroGradient) for the pressure on both, the inlet and the outlet. The problem of the "channel filling" still remains. From my point of view the...

For the simulated 2d case, the film height is 2.5 mm and is located at z=2.5mm. However, in the simulations I will also vary the flow rate and therefore the interface located at z=0 would leed to a...

The obtained...
