goami is on a distinguished road
All friends i am doing a problem based on ejectors for hydrogen fuel cells, but here it has two inlets 1. hydrogen and 2. oxygen i need to mix these two and get an maximum outlet velocity. but i don't know to interpret the pressure ratio in fluent as i need to have a flow choking effect in the throat of the ejector.

this is using k-omega, sst model. i referred fluent manual and gave the pressures accordingly in the pressure-inlet and pressure outlet but getting errors like
divergence AMG SOLVER: omega
divergence AMG SOLVER : temperature
DON'T KNOW WHAT TO DO members please help me out!!!
