Detailed Description

Interpolation WENO Reconstruction Schemes at order 5 at the fixed 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_int_weno_fast_scheme_o5z_rec_compute_weights_both()

subroutine mod_interpolation_weno_fast_scheme_o5z_reconstruction::t_int_weno_fast_scheme_o5z_rec_compute_weights_both	(	class(t_stencil_1d), intent(in)	stencil,
		integer, intent(in)	nx,
		double precision, dimension(nx), intent(in)	dx,
		logical, intent(in)	is_backward,
		class(t_int_weno_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_int_weno_fast_scheme_o5z_reconstruction_backward_apply_fast()

double precision function mod_interpolation_weno_fast_scheme_o5z_reconstruction::t_int_weno_fast_scheme_o5z_reconstruction_backward_apply_fast	(	class(t_int_weno_fast_scheme_o5z_reconstruction_backward), intent(in)	self,
		double precision, dimension(:), intent(in)	values,
		class(t_int_weno_grid_preweights), intent(in)	preweights )

Apply the corresponding scheme.

Parameters

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

		double precision, dimension(:), intent(in)	values,
		class(t_int_weno_grid_preweights), intent(in)	preweights )

Apply the corresponding scheme.
