I am doing a CFD analysis on one of our FSAE models. The problem I am facing is the convergence of pressure. We have tried almost everything from finer mesh to running till 1500 iterations but it doesn’t seem to converge. My residuals don’t go below 1000. Also, due to this, I am getting some absurd results like 4N drag - which of course is not possible for any vehicle.
I checked my mesh quality and stuff but it is fine. I also checked the convergence plot of the inlet, outlet, etc but they all have steady values in the last iterations.
Hope you guys can help me!!
P.S. - Refer to run2 in my project
