Hi all,

I'm working on supersonic inviscid flow simulations in rhoCentralFoam. I test it in flow through wedge and it works well. However, when I use rhoCentralFoam in perforated nozzle, something like separation of flow show in convergent section,like below:

I read the code of rhoCentralFoam. I guess I can run rhoCentralFom in inviscid simulation if I set mu=0. I try set an negative mu but the solver is failure.

Anyone know how to do invsicid simulation in rhoCentralFoam?

Thanks,
chencw
