Upwinding Schemes
 

hello, I have implemented the AUSM and AUSM+ in my code. the interesting thing is that for the same CFL these schemes converges at a slower rate than that of Van Leer and Steger Warming.....the solution is converging slowly ...however, the results are the same compared to Van leer's scheme...but I'm worried whether it has to do with my implementation?? I think it has to do with the stability of AUSM scheme. I'm not sure though....anyone that has experience in these schemes could help ,I would appreciate it. THANKS
