divergence in AMG solver

Hi,
I am trying to model a free surface with the VOF scheme and cannot make the solver converge when using a structured grid. I changed the interpolation schemes, the under-relaxation factors, the cycle type for the x-momentum and turbulent viscosity in the multigrid control panel and the mesh density but I still get this problem whereas when I use an unstructured mesh, it converges correctly. Anyone knows what to do to correct this (except not using a structured grid!)? Regards Ben |
