Ignition
 

Hi, everybody

I wanted to simulate 2-d constant pressure combustion of a methane-oxygen mixture by igniting a small circle area first. I tried to patch 5000 K at the small circle initially but I can't obtain a spherical flame front. How can I get a correct flame front ?

Thanks

I have similar problem too, but I used coal particle as fuel, the reactions did not occur, the conversion is zero. I have tried to patch all calculation domain and initialize with non zero oksigen and CO, however, the results is ame, the reaction did not occur.
