Convergence issues
When running a turbulent case in Fluent, I am getting a message stating that the turbulent viscosity ratio limited to 1.0e+5. Does anyone know how to fix this?

Re: Convergence issues
Are you usung standard-k-e? Try realizable k-e. Perhaps it gets better.

Re: Convergence issues
be patient ... it needs some time to converge ... some more iterations ... try to adjust under-relaxation parameters

Re: Convergence issues
What do you want to fix? Make the message go away - then change the tolerance in the set-up. If the value is unrealistically high, then you would take a different approach.
