My case was actually partially-premixed so I was using the partially premixed model with premixed flamelets to generate my initial condition. Anyway any initial condition with a reasonable...

As I said I'm a bit rusty on the subject, but in my experience EDC was working fine when initialized from the results obtained with a flamelet model. Do you have heat losses in your case? Maybe...

The partially premixed model combined with the flamelet approach can handle detailed mechanisms but it is suitable only for specific combustion regimes (i.e. flamelet regime). My understanding...

If you are satisfied with your results with the partially premixed model I don't see why you should switch to EDC (which is significantly more expensive in terms of computational cost) If you want...

I would suggest you to use your detailed mechanism with the equilibrium partially premixed model to calculate your initial condition, and then switch to EDC using the same mechanism
