dsn2491 is on a distinguished road

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
