Default Coupled solution
Posts: n/a
Hi, I ran some test with the segragated solver with good results. Now I would like to run the simulation with the coupled solver (High speeds are involved) and the solution doesn't converge, the residuals increase and I don't know what to do considering that the mesh was efficient before.

Thanks, Renaud

Hi! What range of Mach number are you considering? I discovered that if you have a good grid there's no problem in usign the segregated for high mach numbers. Luca

I think about Mach 2 or 3 at most. But as I'm looking for a mass flow rate I think that as soon as you take into consideration the compresibility the result will be different. Thanks for your help anyway. Does anyone have a clue?
