Hi everyone,

I am currently using OpenFOAM v1706.

I am trying to declare a class with the internal field of a volScalarField object and a volVectorField object. During class instantiation, I simply want them to be initialized with a uniform zero value. Even though I have copied the constructors used in other OpenFOAM libraries, I am not able to make them work.

Here is the code definition for the volScalarField object.

In .H file, the variable is defined as:

volScalarField::Internal alphaSource_;

Class instantiation in the .C file uses the following code:

    alphaSource_
    (    
        IOobject
        (    
           "alphaSource",
            mesh_.time().timeName(),
            mesh_
        ),   
        mesh_,
        dimensionedScalar("zero", dimVol, 0)
    )

I have attached the error log, but I believe the main error is the following:

In file included from /usr/local/openfoam/v1706/OpenFOAM-v1706/src/finiteVolume/lnInclude/fvMesh.H:58:0,
from phaseChangeAdvection.H:57,

Any help would be much appreciated. I have always come across some or the other error in instantiating a volScalarField object in a class but every time I have used a workaround. Don't want to keep ignoring this forever.
