Hi, I'm trying to develop a new smoother. The problem is that inside a smoother class I can't find any object, that has a reference to some dictionary so I am unable to read some parameters of the smoother.

For example the member function smooth for Gauss-Seidel smoother has the folowing arguments:

void Foam::GaussSeidelSmoother::smooth
(
    const word& fieldName_,
    scalarField& psi,
    const lduMatrix& matrix_,
    const scalarField& source,
    const FieldField<Field, scalar>& interfaceBouCoeffs_,
    const lduInterfaceFieldPtrsList& interfaces_,
    const direction cmpt,
    const label nSweeps
)

Is it somehow possible to read from dictionary inside this class or should I have to implement it as solver which has

const dictionary& solverControls

as argument in constructor?

Thanks in advance

Hi,

- Which parameters of the smoother exactly do you want to access?
- If these are `the` parameters of the smoother, I assume they are members of the class? So, do you really need to access the dictionary?

It is supposed to be a variable parameter of the smoother, i.e. problem-dependent parameter like relaxation factor. Even if it will be a class member I need to read the actual value from dictionary (or set default one but I want to have a choice).

Hi,

- If it is a class member, it is initialised by the constructor or a read() function? so that you can access the dictionary content?
- I am pretty sure, I'm missing something in my understanding. I'm sorry for that.
