Question

What are the two possible variable arrangements for the finite volume method?

(a) Cell-centred and Vertex-centred

(b) Cell-centred and Face-centred

(c) Face-centred and Vertex-centred

(d) Face-centred and Boundary-centred

I got this question in an interview.

My enquiry is from Variable Arrangement in FVM in division Finite Volume Methods of Computational Fluid Dynamics

Answer 1

The correct choice is (a) Cell-centred and Vertex-centred

To explain: Unlike FDM, in FVM, the grid points are taken inside the elements. There are two ways of arranging these elements for a finite volume method. They are cell-centred and Vertex centred arrangements.
