Species Mass Fraction in reactingFOAM
I am simulating methane CH4 combustion using reactingFOAM solver. I want to define a variable which is a function of local mass fraction of CO2, H2O in each computational cell and the cell size.for example:
A=Y_CO2*Y_H2O* cell size
Can anyone help me on how can I write the above in openFOAM coding language to access these variables.
To access species, something like this should work:
const volScalarField& Y_CO2 = composition.Y("CO2");
const volScalarField& Y_H2O = composition.Y("H2O");
Then you should consider that mesh.V() is just a scalarField, so you cannot directly multiply it with the above.
You can let A be a scalarField too and try this:
scalarField A(mesh.V() * Y_CO2.internalField() * Y_H2O.internalField() );
I have not tried the above code, so get back here if you get compilation or runtime problems.
