Default Ignition of the Methane Air mixture

Dear all,


I'm trying to simulate the flame propagation of the premixed Methane-Air mixture. The EDM based simulations of the combustion are all working properly with pretty good results compared to the experiment (at least globally). The main problem I'm facing is the investigation of the flame propagation (and a pressure profiles) from the point of ignition to the flame stabilization (let's say from t=0s to t=5s with reasonably small timesteps). Since the BVM model is using the flamelet library (I don't have CFX-Rif) I'm trying to run the case with use of the source point (and EDM). As the real device (a domestic heater) uses spark plug based ignition, I'm way off the real comparison between experiment and the simulation.


I know that there are many topics regarding the described problem, but none of them with the logical solution. Is there any way to do it without the flamelet library and the let's say BVM?


Thank you in advance,


Ex
