Hi all, I have a question. Can i deal in open foam with dual meshes?
I mean, can i also do finite volume discretisation as node (vertex) centered fv scheme? Thanks in advance! Best regards, Alicja

I know that OpenFoam use collocated grids. But i'm not sure about the FV schemes. Do the finite volume cells agree with mesh cells? Can i also define a finite volume around a vertex (vertex centered) and not around a cell center (cell-centered)? I already looked at the fvMatrix class, and i'm thinking that this is impossible (or hard to do).

thanks!

I modified a little bit the laplacianFoam in the following way:
- first I read a volScalarField f=1 (right hand side)
- next I modify this volScalarField f within the solver to f=sin( pi x )sin( pi y )
- and last i solve -\Delta \phi = f with constant (equal to 0) Dirichlet BC, with \phi : \mathbb{R}^n \rightarrow \mathbb{R}
Is it OK like i did it?
I 've attached the modified solver and the case.

Comments and hints are appreciated!
Greetings,
Ala
