CFD Online Discussion Forums - How to add species source term through fvOptions

Hey,

I use the scalarCodedSource to add source terms to my rho, U and h equations. But I can't seem to find the correct syntax for adding source terms to species equations. In YEqn.H fvOptions(rho,Yi) is present, but if I use Y or Yi keyword as a field I get the following:

Code:

Source motored_pressure_mass defined for field Yi but never used

Any idea how to solve this?

Best,

Bulut

Edit: Maybe I should've been clearer. I CAN add source term to a specific specie if I give it by name :

Code:

fields (rho U h CH4);

But is there a shorthand for doing this all the species in the chemical mechanism I use?
