Hello,

I have been trying to simulate gas induction in a nozzle-ejector geometry. Where gas is en trained because of the flowing water jet. I set up a simpler run where gas density was taken constant and the run converged. However, when I changed the gas behavior to ideal gas it is showing ÄMG Divergence error in all equations. I have been tried first and second order discretization schemes but still nothing. Please help. Thank you.

try small mesh size and under relax all variables specially density and volume fraction
