I want to do a project of ignition of non premixed combustion for a course at the university. This is my first course of CFD and I'm a little lost

I follow this tutorial https://www.youtube.com/watch?v=BnykhP8olUk&t=655s so many times, and without success openfoam 7 openfoam 8 in ubuntu 20.04 and bluecfd in windows temperature goes out of 5000-6000 a lot of warnings of janaf and the result is don't enter fuel or air after calculation.



Chamber in the start is 2000 ° K and with time is cooling with cold air from outlet.


I don't have reactingMixture in thermophysicalPropierties on openFoam by defect use multiComponentMixture I don't know if this is the problem. Finally I tried to copy the mixed properties of SandiaD with worst result.


I guess can be mesh problems but it is the same that in the tutorial.


This is the last configuration with mass fractions of of SandiaD

Solved i put the velocity in the opposite direction
