local_interpolation::local_interpolator_t Type Reference

Interpolation on a set of points with known rst coordinates in elements local to this process. Similar to point_interpolator, but prioritizes performance Only works with arrays of coordinates Performs interpolation with the configured NEKO_BCKND. More...

compute_weights()

procedure, pass(this) local_interpolation::local_interpolator_t::compute_weights	(	class(local_interpolator_t), intent(inout)	this,
		real(kind=rp), dimension(:), intent(in)	r,
		real(kind=rp), dimension(:), intent(in)	s,
		real(kind=rp), dimension(:), intent(in)	t
	)

Parameters

r	local r-coordinates.
s	local s-coordinates.
t	local t-coordinates.
wr	Weights in the r-direction.
ws	Weights in the s-direction.
wt	Weights in the t-direction.

Note

wr, ws and wt must be arrays of dimensions (lx, N) where N is the number of points (size of the r,s,t arrays).

evaluate()

procedure, pass(this) local_interpolation::local_interpolator_t::evaluate	(	class(local_interpolator_t), intent(inout)	this,
		real(kind=rp), dimension(this%n_points), intent(inout)	interp_values,
		integer, dimension(this%n_points), intent(in)	el_list,
		real(kind=rp), dimension(this%xh%lxyz, nel), intent(inout)	field,
		integer, intent(in)	nel,
		logical, intent(in)	on_host
	)

Parameters

rst	r,s,t coordinates.
el_owners	Array of element ids that "own" a given point i.
sampled_fields_list	A list of fields to interpolate.
wr	Weights in the r-direction of shape (lx, N) where N is the number of points to interpolate.
ws	Weights in the s-direction of shape (lx, N) where N is the number of points to interpolate.
wt	Weights in the t-direction of shape (lx, N) where N is the number of points to interpolate.

Note

The weights can be generated with the subroutine compute_weights. Assumes weights have been computed for these points.
