We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Shuai:

An inert can be included in a Chemkin mechanism by putting it in the thermo and transport files with a different name from its chemical twin (also in the species list for the mechanism).  If it is completely excluded from any reactions, you will get a warning when the mechanism is pre-processed that it does not participate in any reaction.  This is ok.  It can also be used as a third body and diluent (if fed at an inlet in the resulting simulation).

Best Regards,

Judy
