Gradient calculated using weighted least-squares on an arbitrary stencil. The stencil type is provided via a template argument and any cell-based stencil is supported:
Stencil | Connections | Scheme name |
---|---|---|
centredCFCCellToCellStencil | cell-face-cell | Not Instantiated |
centredCPCCellToCellStencil | cell-point-cell | pointCellsLeastSquares |
centredCECCellToCellStencil | cell-edge-cell | edgeCellsLeastSquares |
The first of these is not instantiated by default as the standard leastSquaresGrad is equivalent and more efficient.
