3D Preconditioning
Dear Friends,

I am working on 3D preconditioning for Euler flows and am faced with a small problem. For flow past ONERA M6 wing, and M<=0.001, I find that the velcoity and pressure contours are corrupt, right from the first iteration. There is no such problem for M>0.001. In fact, I get a good solution at M=0.01. The preconditioner works well at high M. I make use of Weiss-Smith preconditioner and have validated it extensively in 2D. Can anyone who has worked in 3D preconditioning give some suggestions ?
