Hi,


Forte uses a chemistry set in Chemkin format to define the properties of the gaseous species to be used in the simulation. To import species (and also reactions, if needed), you need to import a chemistry set first. The "Import Chemistry" button can be found in "Models" -> "Chemistry". It is the first icon, which looks like a molecule. Once you click it, you will be prompted to select a .cks (chemistry set) file. In the "data" folder listed there, you'll find several .cks files packaged within Forte. If you just need air, you can choose the one called "Air_NoReactions_2sp.cks". Once the chemistry set is imported, species included in the chemistry mechanism (O2 and N2 in this example) will become available on the initial condition/boundary condition panels.


Best Regards,


Long
