Default On the residual.
Posts: n/a
Hello everyone,

When using fluent to simulate 3D flow field (implicit solver, fine mesh), I find the residuals level off and drop slowly. What should I do? Thank you.

Hi !

On the same subject, I would know what is the good level of residuals for a converged 3D supersonic external flow field (with the coupled explicit solver !!!) ?

I start the computation using the lower courant number, and divergence appears once I increase the courant number. I know this phenomenon relat to the mesh closely, but I don't know what I should do. Thank you!
