Detailed Description

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_o3z_rec_compute_weights_both()

subroutine mod_interpolation_weno_fast_scheme_o3z_reconstruction::t_int_weno_fast_scheme_o3z_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 )

Warning

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

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

Parameters
