Bücherknopf New Member Join Date: May 2016 Posts: 17 Rep Power: 9	Hello, I try to simulate a premixed combustion in a chamber. I inject CH4 and after a certain time I want it to ignite. My problem is now that CO2 appears in my chamber out of nowhere.(it starts at the boundary and I tried EBU and CFM) It seems like the combustion is happening before I even ignited it? Can someone help me and say how I can get rid of this problem? Any suggestion is appreciated.
