Hi all,
I have problems in getting convergence for an unsteady simulation. the continuity residuals do not fall down below 4*10^-3. changing URF's does not make a difference. what surface monitors can I use to check convergence? since there is no steady state solution for my problem, every quantity like pressure and velocity will change in domain. how can I deduce convergence from surface monitors? Below is the picture of the residuals. any ideas? |
