Functions/Subroutines
subroutine	extrapolate_faces_to_faces (field, scheme, axis, index)
	Extrapolation of a field (defined on faces) to neighbour (planar) faces. The reference faces are given by the index ; the extrapolation is done along the axis. The destination (resulting/modified) faces' index are given by index+schemedir (the latter being -1 or +1 depending on the scheme).

Detailed Description

Extrapolate faces to faces.

Function/Subroutine Documentation

extrapolate_faces_to_faces()

subroutine mod_extrapolate_faces_to_faces::extrapolate_faces_to_faces	(	double precision, dimension(:,:,:), intent(inout)	field,
		class(t_ext_scheme), intent(inout)	scheme,
		integer, intent(in)	axis,
		integer, intent(in)	index )

Extrapolation of a field (defined on faces) to neighbour (planar) faces. The reference faces are given by the index ; the extrapolation is done along the axis. The destination (resulting/modified) faces' index are given by index+schemedir (the latter being -1 or +1 depending on the scheme).

Example

Extrapolate the field temperature along the \(y\) plan in the positive direction starting from the je forwardly (hence, to je+1) with the third order scheme:

call extrapolate_faces_to_faces( temperature, ext_scheme_o3_forward_instance, 2, je )

Parameters

[in,out]	field	the array where to extrapolate and where the data is taken from
[in,out]	scheme	the extrepolation scheme

type_ext_scheme , forward or backward

Parameters

[in]	axis	\({1,2,3}\) is the axis \(x\), \(y\) or \(z\) along which to extrapolate
[in]	index	the index from which to extrapolate (ie. the scheme starts at index)
