i am modeling the flow pattern in a nozzle. If i choose air(real gas) without energy equation, i can get correct simulation.
However, a message(Divergence detected in AMG slover) jumped out even before the first iteration after i chose ideal gas and activated energy equation. I've read the relative articles about 'divergence detected in AMG' but i obtained nothing working in my case.
Much appreciate if anyone could supply some suggestions.
