Divergence in modeling cavitation around hydrofoil
 
Hi, I`m modeling unsteady cavitation around 3D hydrofoil and When I`m solving the problem it says "Turbulence viscousity ratio limited to 100000 in cells" and the relusts diverge. Could any one help me?

Hi Mahli,

I guess you should reduce the relaxation factors existing within Solution Controls Panel. Otherwise increase the maximal turbulence viscousity ration under Solve/Controls/Limits.

good luck
