hi! i'm new here in the forum and new in the fluent.
i made a case which suppuosed to be based on the case of ahmed body, acoording tutorials, and the results don't converge after 600 iterations. i wonder what could be the problem. i guess it's not in the mesh, because i followed the tutorials. could it be the models i used? i chose the K-epsilon realizable non eq. what else can affect the convergence? |

There can be many reasons. Please post a picture of the residuals.

They look fine. You should let it running until residuals are lower.

You should monitor the parameters of interest at different points, to make sure it is converged, rather than relying on the progress of the residuals.
