Adding new grain chemistry

Milan Sil

Hello group experts,

I would like to add one reaction to the grain. For example H + CO --> HCO. How to add it?

I added it in "" as COgrn,Hgrn=>HCOgrn:grn_react:1.:0.:0.
I also added "HCOgrn" with its formation enthalpy at OK in KJ/mol on the "chem_species_grn.dat" and binding energy on "chem_hhl.json"
I also tried adding with the new reaction in "mole_reactions.cpp".
But this reaction is not showing when I am trying to see it with save chemistry rates "HCO" "HCOgrn" to see the HCOgrn related reactions.

Please suggest.

Thanks and regards,
