Detailed Description

Reconstruction Schemes with houc at order 3 (at the fixed +1/2 position). This scheme is compatible with non uniform grids.

Note

The fixed position is at the end of the 0's cell (for forward). This is the usual position for reconstruction schemes.

Function/Subroutine Documentation

t_rec_fast_scheme_houc5_apply_fast()

double precision function mod_rec_fast_scheme_houc5::t_rec_fast_scheme_houc5_apply_fast	(	class(t_rec_fast_scheme_houc5), intent(in)	self,
		double precision, dimension(:), intent(in)	values,
		class(t_int_grid_preweights), intent(in)	preweights )

Apply the corresponding scheme.

Parameters

[in]	self	The scheme
[in]	values	The discrete (mean) values of the function
[in]	preweights	The precomputed weights (

Precondition

The scheme has already been initialized

t_rec_fast_scheme_houc5_backward_compute_weights()

subroutine mod_rec_fast_scheme_houc5::t_rec_fast_scheme_houc5_backward_compute_weights	(	class(t_stencil_1d), intent(in)	stencil,
		integer, intent(in)	nx,
		double precision, dimension(:), intent(in)	dx,
		integer, intent(in)	shift,
		class(t_int_grid_preweights), dimension(:), intent(inout)	preweights )

Compute the weights associated to the scheme at each cell in [1:nx].

Warning

as we cannot access to values outside [1:nx], the weights are in fact computed in the computable stencil around the cell.

t_rec_fast_scheme_houc5_forward_compute_weights()

subroutine mod_rec_fast_scheme_houc5::t_rec_fast_scheme_houc5_forward_compute_weights	(	class(t_stencil_1d), intent(in)	stencil,
		integer, intent(in)	nx,
		double precision, dimension(:), intent(in)	dx,
		integer, intent(in)	shift,
		class(t_int_grid_preweights), dimension(:), intent(inout)	preweights )

Compute the weights associated to the scheme at each cell in [1:nx].

Warning
