Extrapolation: grid based routines

Namespaces
module	mod_extrapolate_cell_to_cell_neumann
	Extrapolate cell values toward other cells (usualy ghost cells) with Neumann condition.
module	mod_extrapolate_face_to_cell
	Extrapolate from a field known on faces (u,v,w) towards a cell's center.
module	mod_extrapolate_face_to_edge
	Extrapolate from a field known on faces (u,v,w) towards a cell's edges.
module	mod_extrapolate_cell_to_face
	Extrapolate from a field known on cells (i,j,k) towards a faces.
module	mod_extrapolate_cell_to_face_neumann
	Extrapolate from cells to faces with Neumann conditions.
module	mod_extrapolate_cell_to_point
	Extrapolate from a field known on cells (i,j,k) towards a point.
module	mod_extrapolate_cell_to_point_neumann
	Extrapolate from a field known on cells (i,j,k) towards a point with a given neumann condition (ie. the derivative of the function at the destination point).

Detailed Description

This module provides all the functions and routines to extrapolate a field defined onto the grid. It is divided in submodules depending on the destination node:

• cell_schemes: extrapolate a field to a cell ;
• face_schemes: extrapolate a field to a face ;
• edge_schemes: extrapolate a field to an edge ;
• point_schemes: extrapolate a field to an arbitrary point ;

This module is useful as the developper does not need a priori knowledge of the grid spacing.
