I am receiving the message turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 1430 cells in my simulation. I am modeling a gas-solid fluidized bed reactor. How do I solve this problem? Anyone?

Reduce your relaxation factors

Thanx alot friend. I reduced the under relaxation factors but still the problem persisted for a while and then disappeared!

First,check your mesh quality,refine it.then check your boundary definition
