Error: Divergence detected in AMG solver: uds-0
Hi all,
I'm trying to modify the k and e equations in the k-e turbulence model using user defined scalars. I obtained this error "Error: Divergence detected in AMG solver: uds-0 Error Object: #f" when I modify the viscosity to a non-newtonian viscosity. The viscosity expression is: viscosity=10*ShearRate^(-0.7). The residuals for the continuity increases until the simulation stops. If I teste an expression for viscosity like that viscosity=0.2*ShearRate^(-0.4) the solution converges.:confused: Please someone can help me? It is very important for me solve this question and I don't have any ideia why it is happening :( |
Hello,
Did you got the solution to your problem |
hi dear friend
i see this error when mesh isnt good. do u check your mesh? is your mesh is suitable? |
