Hello
I am trying to simulation a fluid flow problem with reaction. I want to import reaction mechanism from chemkin and utilize the species transport model (volumetric reaction). I am not sure how to initiate the combustion. Some video tutorials on methane-air combustion did not talk about initiation at all. But in version 19.2 I can see there is 2 options: spark and auto-ignition. Is there any tutorial which discusses this issues?
