What do you mean exactly with add physics please ? I don't get it.

- I'll check the coherence between my hardware part and my simulation, but the strange fact is that time calculation seems normal on my computer, excepted after patching. Without patching, EDC calculations are fast it's ok.

- I'm adding gaseous ammonia (fuel inlet composed of gaseous CH4 / H2 / NH3). That's a coaxial burner with a very simple geometry. My EDC model works for 100% hydrogen fuel, but doesn't ignite for 100% methane; while the experiment did it with 100% methane in the burner. 

This information might be useful :  When I do 100% methane combustion using Non-Premixed model : it works. Then switching to EDC, with just species and energy equations solving, creates a detachment (the flame blows off)  and combustion stops.

Thanks for replying quickely !
