Hello everyone,
I don't understand why when I check the result of my simulation (registered with the "f.write_csv" command ) my mass fraction compostion for the first point in the grid (z=0) do not correspond with the initial composition that I specified in the script.
It is something that I observed with cantera/2.3 and cantera/2.5.1.
You can find attached, the script and the mecanism.
Thank you by advance for your help

Hi Alexis,
Have a look at the boundary conditions here: https://cantera.org/science/flames.html#inlet-boundary - the first grid point is part of the solution, and not the imposed boundary condition.
