mod_extrapolate_cell_to_cell_neumann Module Reference

Extrapolate cell values toward other cells (usualy ghost cells) with Neumann condition.

Functions/Subroutines
double precision function	extrapolate_cell_to_cell_neumann (field, scheme, i, j, k, axis, derivative_value)
	Extrapolate from the cell (i,j,k) the field along the axis with a constraining Neumann condition to the previous/next cell (depending on the scheme used).

Parameters

	field	The field defined on the cells
[in,out]	scheme	the finite difference scheme: forward (resp. backward) for backward (resp. forward) extrapolation
[in]	i,j,k	The index of the cell
[in]	axis	The axis (direction) {1,2,3} for {u,v,w}
[in]	derivative_value	The value of the derivative at the extrapolation point

Returns

The extrapolation of field from the cell i,j,k along the given axis to the point indicated by its distance to the cell with the given Neumann condition.
