Hi all What does the massage "Turbulent viscosity limited to viscosity ratio ............in ..........no of cell physically means.

Physically, your model produces too much turbulent kinetic energy. You can check the viscous model,the turbulence specification method and the solution limits on turbulence you are using. Chouaib

increase TVR limit. The warning just means it has hit the default limit in some cells. You may just have cells with high Re in them which may or may not be physical.
