Detailed Description

template<class Scalar, class GridView>
class Opm::VcfvStencil< Scalar, GridView >

Represents the finite volume geometry of a single element in the VCFV discretization.

The VCFV discretization is a vertex centered finite volume approach. This means that each vertex corresponds to a control volume which intersects each of the vertex' neighboring elements. If only looking at a single element of the primary grid (which is what this class does), the element is subdivided into multiple fragments of control volumes called sub-control volumes. Each of the element's vertices corresponds to exactly one sub-control volume in this scenario.

For the vertex-cented finite volume method the sub-control volumes are constructed by connecting the element's center with each edge of the element.

Update the non-geometric part of the stencil.

I.e., indices and neighboring information, but nothing else...
