Turbulent Viscosity ration limited in Sliding Mesh rotation
 
HI All

Can any body let me know what is the possible reason for Turbulent Viscosity ration limited in Sliding Mesh rotation model.The Mesh is dominently very good quality.Is it because of sliding of the mesh over the other interface??

Thanks in Advance

The default "maximum" turbulent viscosity ratio is a bit low. I usually add another 0 to it and only worry if I have problems after that. That may be just for my type of problem though.
