Hello, I'm a new fluent user. I try to compute multiphase flow with the eulerian model. But after the initialisation i get a warning about non-positive volumes. I don't know what the problem is. Could anyone suggest what the failure is? I think it has nothing to do with my mesh. Because I got a solution with one phase model. And when I read the case file and check the mesh, there is also no problem. I would be very thankfull about any answers!!!

Hello, the problem has something to to with the axissymetric option in the solver panel. I think there is a problem with nodes below the x-axis.
