◆ nl_operator_build()

subroutine, public nl_operator_oct_m::nl_operator_build	(	class(space_t), intent(in)	space,

		type(nl_operator_t), intent(inout)	op,
		integer, intent(in)	np,
		logical, intent(in), optional	const_w,
		logical, intent(in), optional	regenerate
	)

Creates the nonlocal operators for the stencils used for finite differences.

This code loops over grid points and finds the stencil to be used by looking at the coordinates of the points in the stencils. All the consecutive points that are using the sames shifts in relative coordinates are considered to be within one stencil application. The number of them is opri The map oprimap contains the map (mesh index ip) -> stencil (between 1 to opnri) The inverse map oprimap_inv contains the start and end indices for a given stencil, such that oprimap_inv(ii):oprimap_inv(ii+1) is the list of points sharing the same stencil index With this, all points within oprimap_inv(ii):oprimap_inv(ii+1) have the same value in oprimap

Parameters

[in]	np	Number of (local) points.
[in]	const_w	are the weights constant (independent of the point)
