I can not achieve ignition in combustion chamber.
I am working on modeling a 2D combustion chamber which receives 5 inlets with 10 species. Among them the fuel is CH4. My problem now is that I can not start an ignition. I could summarize my problem as follows:
I tried using the 'patch' with a temperature of 2000K after a few iterations, but it does not work (but I am pretty sure that it worked for me a week ago, so I do not know what to think now). Now is definitely not working.
I am using a steady simulation. The mesh is pretty coarse now but it works the same way with the good one. I just want to achieve a good modeling before starting with a fine mesh.
Thanks in advance,
