Thrust Vectoring problem
 

Hi,

I'm trying to model a fluidic thrust vectoring convergent divergent jet engine nozzle in fluent 6. It's supersonic flow, but the only solver I can avoid divergence with is coupled explicit, which refuses to converge. I've tried starting with a simple model and gradually adding complexity, but as soon as I activate compressible flow I get divergence.

Can anyone offer any advice?
