Level set simulation

[Andrea_P]

Hi,
My simulation always stops at 35 iterations, I have modified velocity, time and relaxation factor, but it always stops. I can't find the error, maybe it depends on the mesh. I should observe fluctuations which are created by the obstacle in the middle. These fluctuations should move to the inlet and outlet borers. I attach the zip folder. Thanks in advance for your help.
