January 21, 2002, 11:51	significance of viscosity ratio	#1
phil Guest Posts: n/a	During iterations running the turbulent model I am regularly getting the report turbulent viscosity limited to viscosity ratio of 1e5 in xxx cells. I cannot find in the Fluent manual what the viscosity ratio is. Is it simply the definition of viscosity ie ratio of shear stress to shear rate? What does this warning signify in the model, are there common causes which lead to this problem?
