sufjanst Member Join Date: Mar 2016 Posts: 73 Rep Power: 10	Hello everyone, I have a problem in combustion modelling. I have 4 burner in a combustion chamber. I want to simulate a failure in one burner. I changed the inlet to 'wall' and initialized the area above the burner. But after a few iterations fluent starts to create methane and a combustion in the burner. I have no idea where the methane comes from and it doesn't make any sense. I use PDF Partially-Premixed-Combustion with ECFM, k-omega and non-transient... Does anybody have a workaround or an idea for this problem? Cheers sufjanst
