Utilise reduced kinetics mechanism (ARM19 etc.)
Hi all,

I have come across multiple papers which make reference to Fluent's "hard coded" augmented reduced mechanism, ARM19. I would like to use this mechanism within the composition PDF transport model, however after searching and searching, i cannot find out how to implement this mechanism with ANSYS 14.0.

I have found reference to files named "arm19.che" and "therm.dat", yet these files do not exist in my directories.

If it is hard coded, then no file importing would be necessary? Can someone please help with the process of utilising/enabling this mechanism?

Good Luck

Thank you Vnm,

However the link produces a 404 Http error for me. Do you have a copy of the file or a name and author of the paper so i can attempt to retrieve it from the Uni Library?

Hi Clarkie_49,

I have the same problem; I've searched everywhere how I could implement a reduced mechanism in FLUENT but no way.
I'm confused because I don't find any arm9 file (should it already be in the FLUENT code?) , I don't know what to do with the CKWYP fortran subroutine.
Have you found something?


PS: the link you couldn't open should be : but not really helping
There's also this one
