procedure, pass(self)	apply_fast (self, values, preweights)
	Apply the corresponding scheme.
Public Member Functions inherited from type_rec_fast_scheme::t_rec_fast_scheme
procedure, pass	init (self)
	Init the scheme.
procedure	precompute (self)
	Precompute all weights for cells and faces.
Public Member Functions inherited from type_int_fast_scheme::t_int_fast_scheme
procedure, pass	init (self)
	Init the scheme.
procedure	fast_compute_stencil (self, preweight, step, steps, derivative)
	Compute the scheme's weights with a generic function. The generic version should works fine as it will only be called once when computing preweights.
procedure	precompute (self)
	Precompute all weights for cells and faces.
procedure	fast_interpolate (self, preweight, step, steps, values, derivative)
	Interpolate (apply the fast scheme).
procedure	apply_fast (self, values, preweights)
	Apply the fast scheme with given values and preweights.
procedure	compute_stencil (self, step, steps, derivative)
	Dummy function as it's not available for fast schemes.
procedure	interpolate (self, step, steps, values, derivative)
	Dummy function as it's not available for fast schemes.
procedure	apply (self, values)
	Dummy function (existing for architecture needs).
Public Member Functions inherited from type_int_scheme::t_int_scheme
procedure, pass	init (self)
	Declare a stencil base on its starting and ending relative indices.
procedure	compute_stencil (self, step, steps, derivative)
	Compute the stencil values.
procedure	apply (self, values)
	Apply a scheme to given discrete values at a point in the stencil (usualy the node at x_{i+1/2})
procedure	interpolate (self, step, steps, values, derivative)
	Interpolate at step with values. The steps and the values are given in interval 'index_start:index_end'.

Member Function/Subroutine Documentation

compute_preweights()

procedure, nopass mod_rec_fast_scheme_houc5::t_rec_fast_scheme_houc5_backward::compute_preweights ( 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 )

static

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.
