Default CFdesign behaviour in coarse and fine mesh
Posts: n/a
Dear Friends,

I am using Cfdesign software for CFD simulation. I can get converged solutioin in coarse mesh in different models but when I refine mesh it diverges! I have seen this behaviour in two different model. Does it mean that Cfdesign is so sensitive to Round of error? I appreciate to receive your idea and thoughts about this matter.

Thanks farhad
