I met some errors in simulating a turbulent flow in a 3d channel model: 1, turbulent viscosity limited to viscosity ratio of 1.000000e+5 in 12092 cells; 2, Error: floating point exception; Error Object: #f. Can someone tell me the reasons and what I should do the next? Thanks so much!

The turbulent viscosity limitation usually happens if you set wrong boundary conditions for turbulence, or if you're using a mesh which is not fine enough in some point of your domain.

Try to plot contours of turbulent viscosity ratio to see where the limitation takes place.
