Hi guys~If you have used this model,please help me.

After setting all values as the User Guide said, I got an unburned result.

By checking it, I found The turbulent flame speed was just equal to the laminar flame speed, which was relatively too low to support propagation of flame.
I calculated the LFS using CHEMKIN-PRO and GRI 3.0.

Is this normal? Or do I have to switch on sth in order to make the program calculate TFS?

Many thanks~

PS:Steady, Pressure-based, Viscous-SST, Adiabatic, C equation, Zimont, Inlet C=0, Pressure-OUTLET C=1, Patch the flow domain with C=1.
