I am trying to create a custom field function for getting an equivalence ratio of a mixture of Air and H2.

I have 2 intakes, one intake where there is a mass fraction of 0.9 Air, 0.1 H2 and the second intake of where there is only H2 (0.0 Air, 1.0 H2). After the second intake, downstream I need to check the Equivalence Ratio. But I am getting very high values of equivalence ratio. I think the formula I am using is wrong. Here is the formula I am using

${MassFractionH2}/0.02916
