I'm having problems with the Jameson scheme. I have already used it for external flows, and I found it was really good for steady state calculations. Now I' m using it in a finite difference method for cylindrical coordinates. It seems unable to "hold" a steady solution, I mean, even if the initial condition is an Euler steady solution (basiclally I m fixing a balance between centrifugal force and pressure gradient), and this steady solution is stable, the solution after a while seems to diverge. CAn anyone suggest me what's happening?

Hi!

The Euler equations maybe not sufficient to you solve your problem. You´ll try add the viscous terms? If you have a centrifigal force, you must use the roting frame terms, where the coriollis force is present.
