When to know if residuals have converged or not?
I am running simulations for wind flow across a building. My scaled model is halved as i have used symmetry boundary conditions. I am somehow not getting convergence conditions. My residuals are all oscillating and they all follow same oscillating pattern together. Please let me know how to decide solutions have converged or no. And what solution scheme should i use? I used SIMPLE and SIMPLEC but they dont make much difference. PFA-Attached residual plot |

search the forum, this has been asked many times. Monitor other scalars, the ones that your are interested in. Also mass flow change accross in and out. Good luck.
