convergence problem with compressible flow

January 30, 2009, 00:20

Hi ,

I am having one inlet boundary and two pressure boundaries. one pressure boundary allows flow into domain while other allows it go out. I am using density as function of pressure and temperature.I have done the simulation,residuals have gone below 10-4. I did post processing ,i have found that total pressure contour is not correct. I did several runs but the problem persists. I have also found that pressure(PFAV) at pressure boundary is fluctuating. Please,can anybody tell me why this is happening?
