Hi all,

I am just wondering, if I am getting things correct (but my analysis will show that I am not correct). Assuming that we do have an object based on a volScalarField which is actually a GeometricField. For this field, we can apply the function named mesh(). This function is not implemented in the GeometricField class but as this class includes the DimensionedField class, we can see that it is implemented there. As I cannot find any other function named »mesh()«, I expect that this is correct. The mesh function returns a reference to an object based on the class Mesh:

const Mesh&  mesh() const;

The class Mesh is actually

GeoMesh::Mesh Mesh;

So while we call the mesh function, e.g.,

volScalarField T = ...;


const Mesh& foobar = T.mesh();

we get an object of type Mesh (GeoMesh::Mesh). I guess there is already a mistake in my analysis as I have no idea how we can do the follow:

.... = T.mesh().ddtScheme("foobar");

The ddtScheme function here is based on the class fvSchemes, which is not inherited by GeoMesh. Actually the code:

T.mesh()

has to return somehow the reference to the fvMesh class because this class inherites the functions from the fvSchemes class. Furthermore, one can program the following:

const fvMesh& test = T.mesh();

However, I do not get the connection between the function mesh() that returns the fvMesh object. I am working with FOAM for 9 years now and I do not get the simplest things. Yesterday I saw a report on the TV that the youngest German hacker is 18 years old and has a security company in Hamburg with 23 employees. And I am not even able to connect the mesh() function call to the fvMesh class.


The only thing that I could image is the following:

• the GeoMesh class is a template based on the class MESH
• the GeoMesh is constructed somewhen using the fvMesh class
• If so, the returned object of the DimensionedField mesh() function, which is of class Mesh (typedef GeoMesh::Mesh) would return an fvMesh object because the Mesh is:

typedef MESH Mesh

• and while the returned object of the function mesh() of the DimensionedField class is of type Mesh, while MESH is the class template parameter of the GeoMesh class, the type Mesh could be a fvMesh (related to the construction of the GeoMesh object.

I hope that the last statement was clear


Any hint is welcomed.
Thanks in advance.
