I am unable to find the option to use CSP or QSSA mechanism reduction in Chemkin-pro. Where is this option located? In the documentation it says to select CSP from drop down option, but chemkin pro does not have a drop down option to select mechanism reduction procedure.nnAlso, is there an option to use ARM-19 mechanism in fluent?.

Please check chapter 2.3.1 in the R 2020 R2 Chemkin-Pro User?s Guide. The drop-down menu needs to be activated under Edit > Preferences.nnConcerning ARM-19 mechanism:nIf you google for ?how to use arm-9 mechanism in fluent?, you get two results from cfd-online with hints how to use the ARM-9 and ARM-19 mechanism in fluent.nn

Thanks for your helpful reply. I was able to activate the option in the preferences and see QSSA option now.nnI did check out the google searches you mentioned. However, they aren't really helpful, as I have tried using their hint's, without success.n
