type_rec_scheme Module Reference

Grid nodes Reconstruction Schemes type The difference with the t_int_point_1D resides in that the scheme is defined in a narrowed band between index_start and index_end. The stencil is centered around the index 0, the step is relative to this node. More...

Data Types
type	t_rec_scheme

Detailed Description

Grid nodes Reconstruction Schemes type The difference with the t_int_point_1D resides in that the scheme is defined in a narrowed band between index_start and index_end. The stencil is centered around the index 0, the step is relative to this node.

Function/Subroutine Documentation

t_rec_compute_stencil_generic()

subroutine type_rec_scheme::t_rec_compute_stencil_generic	(	class(t_rec_scheme), intent(inout)	self,
		double precision, intent(in)	step,
		double precision, dimension(:), intent(in)	steps,
		integer, intent(in), optional	derivative )

Compute the stencil with a generic reconstruction procedure.

Note

This can be overloaded by a deriving scheme with an optimized version

Parameters

[in,out]	self	the element
[in]	step	the step where to interpolate relatively to the reference node 0 center
[in]	steps	the control volumes between the node values (of size N)
[in]	derivative	(optional) the derivative number: 0 (default) for value interpolation, 1 for first derivative, etc.

dd(j,i) contains the weight associated to the j^th point of the (i)^th derivative

t_rec_compute_stencil_generic_debug()

subroutine type_rec_scheme::t_rec_compute_stencil_generic_debug	(	class(t_rec_scheme), intent(inout)	self,
		double precision, intent(in)	step,
		double precision, dimension(:), intent(in)	steps,
		integer, intent(in), optional	derivative )

This function is defined for debug purposes only (in order to verify new fast schemes)!

dd(j,i) contains the weight associated to the j^th point of the (i)^th derivative
