extendedCellToFaceStencil Class Reference

Calculates/constains the extended cell-to-face stencil. More...

#include <finiteVolume/extendedCellToFaceStencil.H>

Detailed Description

Calculates/constains the extended cell-to-face stencil.

The stencil is a list of indices into either cells or boundary faces in a compact way. (element 0 is owner, 1 is neighbour). The index numbering is

  • cells first
  • then all (non-empty patch) boundary faces

When used in evaluation is a two stage process:

  • collect the data (cell data and non-empty boundaries) into a single field
  • (parallel) distribute the field
  • sum the weights*field.
