hi CFD worker
Convergence -Accelerating convergence -Under-relaxation - Increase under relaxation factors under-relaxation factors slow down the rate at which the solution changes during the iteration and in transient solutions increase the Courant number: Courant number is the ratio of a time step to a cell residence time hope this may give some idea about Courant NUmber all the best anand |
