dsn2491 New Member Aditya Join Date: Dec 2011 Posts: 28 Rep Power: 14	Hi, I am tryin to simulate a M=2.1 shock wave in FLUENT. I have defined a UDF for the boundary conditions and using a courant number of 1. Immediately after the calculation starts the values deviate a lot frm the set values and the calculation from there on goes haywire. Can someone tell me why this is happening and wat are the things i need to look into for rectifying the problem Thanks!!!
