What should we do if 2 out of 10 CFD models do not converge? We need to compare CFD results amongst all 10 cases but 2 of them not converged. If we change under-relaxation factors for 2 of these, will our comparison be valid? What do people normally do when encounter this problem?

Dear rsi;
if this problem is fixed by changing the relaxation factors, your comparison is valid. relaxation factors does not affect the converged results. they only adjust the convergence rate. under relaxation factors are just useful tools to help the convergency.
does it help?
