mod_extrapolate_faces_to_plane Module Reference

Extrapolate faces to a whole plane.

Functions/Subroutines
subroutine	extrapolate_faces_to_plane (field, scheme, ext_step, axis, index, destination)
	Extrapolation of a field (defined on faces) to a destination discrete plane. The reference faces are given by the index ; the extrapolation is done along the axis at a distance of ext_step.

extrapolate_faces_to_plane()

subroutine mod_extrapolate_faces_to_plane::extrapolate_faces_to_plane	(	double precision, dimension(:,:,:), intent(inout)	field,
		class(t_ext_scheme), intent(inout)	scheme,
		double precision, intent(in)	ext_step,
		integer, intent(in)	axis,
		integer, intent(in)	index,
		double precision, dimension(:,:), intent(out)	destination )

Example

Extrapolate the field temperature along the \(y\) plan in the positive direction starting from the je forwardly (hence, to je+1) at a distance of 0.12d0 with the third order scheme:

call extrapolate_faces_to_plane( temperature, ext_scheme_o3_forward_instance, 0.12d0, 2, je, result )

where result is a double precision, dimension(:,:) coherently allocated.

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]	ext_step	the distance to which extrapolate (distance to the index faces)
[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)
[out]	destination	the resulting discrete plane
