Hello, I'm trying to modify some files of a program in openfoam. Inside of one of this files (file.C) I have member functions as shown below.
My question is what the usage of .primitiveField(), .primitiveFieldRef and boundaryFieldRef() is. I could not find information regarding this topic and don't understand why they are used. Thank you in advance for your help.

const surfaceVectorField& wss,
surfaceScalarField& phi,
)const
{

UpdateValues(wss.primitiveField(),
,phi.primitiveFieldRef(),
);
forAll(wss.boundaryField(),patchI)
{
UpdateValues(wss.boundaryField()[patchI],
,phi.boundaryFieldRef()[patchI],

);
}
}
