Premix CH 4/Air flame with scheme GRI12

This test case concerns the reduction of the detailed scheme GRI12 for a premixed $CH_{4}$/air flame at P = 1 bar and initial temperature of the oxidizer and the methane at 300 K, for an equivalence ratio of 0.75. The target species are : $O_{2}$, $CO$ and $CO_{2}$.
