Hi
I simulate methane combustion using one step mechanism and the solution (contour) of methane mass fraction has a one value at all the surface with squares in all the figure (the figure is in the attachments)
any help

Note: the species equation for methane and the energy equation converge to a very small residual (about 10^-12)
