gas injection in AVL FIRE (please help me)
 
Hi guys,

I want to inject gas from 1mm diameter nozzle to a constant volume chamber.
for inlet of injection I use total pressure boundary condition. but after some time step an error massage "the solution is diverged" is appeared.

What boundary conditions should I use?
Would you please tell me about important adjustment in solver control?

Thanks,
