NO FLOW FIELD
 

Dear Fluent Users,

I have a 3D model that is looking at a supersonic jet exiting from a nozzle onto a flat plate. I made two mesh column. The inner column and then an outer column which is the vacuum chanber. I have a pressure inlet, and a pressure outlet. The strange thing is that I do not have any flow where the jet should be. I looked at various cross sections, but I do not see any flow. It is Mach 1 at the throat area of the nozzle. I made the inner column faces as interior bc. do you have any ideas?

hope to hear from you soon. -Manish

THANK YOU!
