nnThank you for responding.nI will try using the D/1000 mesh again then. It just takes too much time though. My colleague and I, are using the same mesh so I can't alter the mesh as much as I want to. nAs you can see in the residuals in my post, the residuals start diverging after a while, is reducing the relaxation factor all I can do to ensure that the residuals decrease or converge? I am already running second order for all discretization fields.nRegarding results having no order, the results for all Cd, Cl, and Cm are not organized in the sense they don't show a pattern, all of those plots were like the residual graph I have attached for this post. (I am home so I don't have the screenshots here, I can attach them tomorrow).nn
