hello
I hope you people are doing well. During my fluent's simulation using k-Epsilon model the residual level reduces (trys to converge) but at some point in the calculation the residauls for k and epsilon starts to diverge but as I have set a lower level for the residuals of K and epsilon. I still get a converged solution. 1. My question is that if the residuals for K and epsilon or any parameter show a diverging trend and the solution gets converged. Is it acceptable?or the residuals are always supposed to show a converging trend? (If we only observe residuals for convergence criteria). 2. My second question is that As the residuals for K and epsilon showed a diverging trend, I kept their convergence criteria to 0.005 each. Is this an acceptable limit? Thank you.
