Reply To: Fluent Combustion Problem

1. If the Eddy Dissipation Model (EDM) does not produce combustion, then two most likely reasons are:

flow is not turbulent. Please check turbulence levels (Re, or turbulent viscosity ratio).

Not all reactant species mass fractions are nonzero, and at least one product species mass fraction is nonzero at the beginning of the iteration. Please patch some nonzero values.

2. The EDC model requires adequate turbulence and artificial ignition. It's better to start the EDC calculaiton from a reasonably converged EDM solution or solution from "Relax to Chemical Eqilibrium" calculation.
