Combustion model on SI simulator in Chemkin

[ss00321]

The SI model uses the flame-sheet approximation for fuel combustion, which assumes complete combustion occurs instantaneously.

I would like to disable this option to use a detailed kinetic in the SI Simulator, similar to what is done in other reactor models, such as Batch or PFR.

However, I cannot find options such as “Burned Gas Chemistry: Finite-Rate”, “Enable Chemistry in Burned Zone”, or “Post-Flame Kinetics” to prevent the burned zone from using equilibrium.

Is it necessary to modify the model through programming to achieve this?

If so, could someone please show me how to implement it?
