hello,

I use RANS to similate open-channel flows and density flows. The eddy viscosity is calculated by the k-epsilon model. However, some code put upper limit on the eddy viscosity which make sure that the eddy viscosity is always below 100×snu (100 times of Coefficient of kinematic viscosity, 1e-6). I want to konw why does this limitation and is there any suggestion on the limitation.

Thanks in advance
