Hi,
I am simulating a turbine and residuals are as follow: As you see, the convergence is not good, what do I do until the convergence is became better. First, Under relaxation factors are 0.1and 0.1 for pressure and momentum.and then 0.3 and 0.7 respectively. Also, mesh is structure and very good. Thanks, Best, Aja |
