xiaofish Guest Posts: n/a	I am now using Spalart almarmas + 2nd order upwind to do simulations in FLUENT. but it is very fast to diverge after just a few steps of iterations. My mach number is around 2 and Reynolds number in order of 105. So how to solve the divergence problem? How can i get some reasonable initiation field for the iterations to continue? Thank you very much in advance!
