second order upwind cause divege !!
Dear friends
I`ve developed a non linear eddy viscosity model with UDF.when I use the first order upwind for all transport equations it is OK! solution converged. But when I switch on second order upwind solution is going to diverging.up to an error "turbulent viscosity limited to....." and finally floating point. how can I solve this diverging ? |
