fvMatrix to volScalarField coversion ?
 

Hi everybody,

I'm try to use the combustion model class of openfoam, it has a member function that returns the source therm for species equations (Reaction rate):

virtual tmp<fvScalarMatrix> R(volScalarField& Y) const = 0;


If I understand well, this funcion is overloaded with the calculation way provided by reaction model for R that is selected at runtime. it function returns a fvScalarMatrix. My question is if I want to define a new volScalarfield, for example, Rates, It is possible to utilices this fvScalarMatrix and define a volScalarField , exists any form to make this conversion ?

Any advice will be graatly appreciated, thanks in advance

Hi Felipe,

I have the same problem. Have you succeed?

Hi,

As you know the method is abstract and needs to be overloaded. But what you are trying to achieve is not clear to me. If you want a volScalarFeild, then you can just look for where R has been called and use the input argument of it. You already have that volScalarField (y), why convert it from R?

You have to multiply by the respective field to get volScalarField from fvMatrix (check how it is used in Qdot function in singleStepCombustion.C). Basically, you need to do
