Hello everyone.

I am trying to simulate methane-air combustion in Ansys Fluent using EDC model and GRIMech 2.11 detailed mechanism(277 Reactions and 49 species) but i get no combustion. Any suggestions to solve this problem?

Case:

• Pressure-based solver
• Realizable k-epsilon model
• Species transport model with EDC model
• Air and CH4 enter chamber from 1 inlet in 2D model at 673K
• Inlet is velocity boundary with swirl component and outlet is pressure boundary

i also tried patching temperature, reactants and products.
