In 2dd problem Axisymmetric Vof In
 Multhiphase Model 2 components  visosus model kepsilon 2 eqn standard  standard wall functions the solver that it doesn't converge the iter continuity  me from the following mistake: Error: Internal error at line 743 in file 'amgif.c'. divergence detected in AMG solver Error Object: () turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 132 cells. Thanks for your attention. Bey well, 
Re: Axisymmetric Vof
Hallo What VOF scheme did you use? It should not have any problem to get converged solution. Start with a smaller time step if you do time dependent simulations.

Multiphase Model
Geo reconstruct, Courrant Number 0.25 Thank You 
Re: Axisymmetric Vof
I don't see any reason why it doesn't work.

Re: Axisymmetric Vof
Does it converge in 10 iterations? Whats the convergent criteria?
CFD MAN 
Re: Axisymmetric Vof
They are the Iteration max for step, but doesn't converge also with Max Iter = 50.
Could question but perhaps depend to type of mesh ? Thank you 
Re: Axisymmetric Vof
I am pretty sure that its the mesh quality. I have been using VOF with geo for more than 2 years now, I didn't have any major difficulties.

Re: Axisymmetric Vof
Does it know pointing to me a few books that treat any problem of Mesh in turbulent regime? Thank you.
