Hi Ren - Thanks for the note; the Integration Parameters are below.  I have not used ISAT before this project with Fluent, and the settings there are default.  Do you think I should reduce the ISAT tolerance?

The fuel is a mix of 65% H2, 35% NH3, molar basis, and I'm using a mechanism from Stagni et al, 2020, which is currently one of the better ones available for predicting N-H-O reactions in ammonia combustion (31 N-H-O species, 203 reactions, https://pubs.rsc.org/en/content/articlelanding/2020/re/c9re00429g ).
