Detailed Description

Creates upwind stencil by shifting a centred stencil to upwind and downwind faces and optionally removing all non-(up/down)wind faces ('pureUpwind').

Note: the minOpposedness parameter is to decide which upwind and downwind faces to combine the stencils from. If myArea is the local area and upwindArea the area of the possible upwind candidate it will be included if (upwindArea & myArea)/magSqr(myArea) > minOpposedness so this includes both cosine and area. WIP.

Constructor & Destructor Documentation

extendedUpwindCellToFaceStencil ( const cellToFaceStencil stencil,
const bool  pureUpwind,
const scalar  minOpposedness 
)

Construct from mesh and uncompacted centred face stencil.

Transports facestencil to create owner and neighbour versions. pureUpwind to remove any remaining downwind cells.
