I want to investigate Jet in Hot Co-flow (JHC) burner with the Eddy Dissipation Concept (EDC) model. Reactants are (H2 and CH4)

As I found out, Species Transport Model should be chosen for EDC model. But if we select Species Transport Model, How can we define Methane and Hydrogen as Reactants?

which software do you use?
I work with Ansys fluent and there you defin eyour reactants in the "materials"-list and then as boundary conditions.

I'm using Ansys Fluent 18.2
After selecting Species Transport and Volumetric options, there is a list of mixture materials, but none of them is Methane + Hydrogen

If we select Methane-Air, Hydrogen in not available in "Select Boundary Species"

At Setup->"materials" you have to define a new mixture.

I added Hydrogen in Setup > Material
but Hydrogen can't be found to define Mass Fraction in Species tab in Boundary condition for fuel-inlet
