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 Vijay,

Thank you for your response. I've indeed noticed that the GRI mechanism is mainly suitable for natural gas combustion, but I assumed it might also contain the kinetics for ammonia combustion. Now, I understand that I'll need a different mechanism. 

I've been trying already to import the mechanism by Nozari (https://doi.org/10.1016/j.fuel.2015.06.075). However, as soon as I import the mechanism, Fluent doesn't give any error, but Fluent just shuts down. I'm running Fluent from Workbench. Would this imply that the file can not be read correctly perhaps? Or can this be caused by something else?
