Hi，

I wanted to use the G equation model to calculate the combustion process of a PFI gasoline engine, but I encountered the following problems：

1. I have imported a laminar flame velocity table into G equation model, why do I need to set at, ap, mt, mp, and dilution species mass fraction to calculate laminar flamespeed?
2. Is the laminar flow flame velocity I calculated using the 0-D simulation sl or sl_ref?
3. I learned that there are two exponents that need to be benchmarked against the experiment, are these two exponents Temperature exponents constant(γ) and Pressure exponents constant(β)?
4. Are Temperature exponent slope(mt) and Pressure exponent slope(mp) used to calculate instantaneous local γ and β? If combustion is carried out at a chemical equivalent ratio, do the values of mt and mp not affect the calculation of the laminar flamespeed?

Thanks for your help.
