Reply To: Ignition doesn’t start with GRI-Mech for methane

Hi Vijay,

I'm no longer working on this project, because I couldn't make it work, but thanks for your answer.

Just to clarify, in both case I was trying to burn a blend of Methane-Air. But in one case, I was using the GRI Mechanism (no ignition obtained), and in the other case, I was using the default mechanism provided by Fluent named "Methane-Air", with only 1 or 2 reactions (here I had an ignition).

Then I guess you're right, the problem might be that the systme wasn't properly mixed. I based my simulations on eq. ratio and tested various different cases, but it never worked...

Thank you
