Modelling Unsteady Compressible Flow

Vince!

Dear All,

I'm using Fluent to run some tutorials and, more exactly, I'm working on the one called: Modelling Unsteady Compressible Flow.

After to have made the steady simulation, I have uploaded the pexit.c file to begin the unsteady simulation. But, a message error comes out every time I clik on the Interpret button in the Interpreted UDFs window.

May somebody either tell me how to escape this problem or send me the good file (pexit.c)?

Thanks in advance,

cheers, Vince!
