Data Types
type	local_interpolation::local_interpolator_t
	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...

Modules
module	local_interpolation
	Routines to obtain interpolated values on a set of points with known rst coordinates in elements local to this process.

Functions/Subroutines
subroutine	local_interpolation::local_interpolator_init_3arrays (this, xh, r, s, t, n_points)
	Initialization of point interpolation.
subroutine	local_interpolation::local_interpolator_init_1array (this, xh, rst, n_points)
	Initialization of point interpolation.
subroutine	local_interpolation::local_interpolator_free (this)
	Free pointers.
subroutine	local_interpolation::local_interpolator_compute_weights (this, r, s, t)
	Computes interpolation weights \( w_r, w_s, w_t \) for a list of points.
subroutine	local_interpolation::local_interpolator_evaluate (this, interp_values, el_list, field, nel, on_host)
	Interpolates a list of fields based on a set of element ids.
subroutine	local_interpolation::jacobian (jac, rst, x, y, z, n_pts, xh)
	Constructs the Jacobian, returns a 3-by-3 times number of points where \( [J(\mathbf{r}]_{ij} = \frac{d\mathbf{x}_i}{d\mathbf{r}_j}\).
