You can use the reaction mechanism described in,
Liu, Yao-Dong, et al. "Enhancement on a skeletal kinetic model for primary reference fuel oxidation by using a semidecoupling methodology." Energy & Fuels 26.12 (2012): 7069-7083.



The above is used in our (CONVERGE STUDIO) GDI example case from where you can grab the mech.dat and therm.dat


Best,
Nitesh

Hello Nitesh,

Thanks for your concern. I used the files you mentioned, but I encountered the following error:

JOB ABORT invoked by rank 0:

2375 ERROR: species C8H18 specified in initialize.in not found in mech.dat or species.in

What can I do?

Serdar,


Please change the name of the species from "C8H18" to "IC8H18" in initialize, boundary, spray etc *.in files.
