boundary condition at nozzle exit
 

What should be the boundary condition used for nozzle outlet surface? Pressure far field or presure outlet, both are resulting different results. Exit of nozzle is at ambient condition.

Same case file is not going to converge for diffirent inlet pressure ( low pressure values ) while other conditions are same.

Anyone can help!

You should use pressure-outlet. Pressure-far-field should be used for aerospace external flows to set the flow-conditions. Luca
