turbulent viscosity

March 9, 2006, 18:10

Hi,

if the limited turbulent viscosity ratio warning appears several times but convergence is finally reached, is the validity of the solution affected by the warning? Do you suggest to adapt the mesh of the cells which cause the problem?

Thanks in advance

Just in case you didn't realise you can increase the limits of the turbulent viscosity ratio to a maximum of 1e+20. (Go to solve, controls, limits).

chnaging the turbuleent specification methods in the inlet panel to intensity and hydraulic diameter wiil not give such problem
