Hi guys, I'm kind of new to OpenFoam and C++. I'm trying to understand how a solver generally "works", and I'm a bit confused by something here.

In createFvOptions.H, there is the initialization of a fv:: option object as:

fv::options& fvOptions(fv::options::New(mesh));

The fv:: options::New(mesh) returns a reference to a newly created fv:: option object, and if I'm understanding correctly, this is suppose to be a copy construct. However, in the definition of fv:: options in fvOptions.H, the copy constructor is deleted as:

options(const options&) = delete;

So I clearly misunderstand sth. here since the solver works fine.

In your code

fv::options& fvOptions(fv::options::New(mesh));

fv:: options::New(mesh) returns a reference to the object (not the object itself). This reference is copied into fvOptions (not the object inself). Copy constructor of fv:: options isn't invoked here.

Thanks a lot! I was being stupid.....
