Hello,
I would add a function in the OF solver, this function is packed as .so library and is included while wmake the OF solver. In my function I need mesh data, for example the neighboring cell or the coordinate of cell center.
My problem is, how could I access mesh in my function? I have included head file in my library to recognize fvMesh class and my idea is

//----In the OF solver------
meshread(mesh)

//----In my owning function
void meshread(fvMesh)

void meshread(mes){
,,,reading mesh data
}

I have compiled the solver and gotten the following error Foam::fvMesh::fvMesh(const Foam::fvMesh&) is a private within this context
meshread(mesh)

I would be grateful if someone shows me how to access mesh correctly. I could copy mesh data in my defined variable and send to my owning function, but it is inefficient.
Thank you
