type	legendre_rst_finder_t
	Type to compute local element (rst) coordinates for a gives set points in physical (xyz) space on a SEM grid. More...

Functions/Subroutines
subroutine	legendre_rst_finder_init (this, x, y, z, nelv, xh, tol, max_iter)
subroutine	legendre_rst_finder_free (this)
subroutine	legendre_rst_finder_find (this, rst_local_cand, x_t, y_t, z_t, el_cands, n_point_cand, resx, resy, resz)
	Given a set of element candidates containing the given points and computes the local RST coordinates for those points. This subroutine supports both CPU and device (GPU) execution, depending on the configugered backend of NEKO_BCKND_DEVICE.
subroutine	find_rst_legendre_device (this, rst, pt_x, pt_y, pt_z, el_list, n_pts, resx, resy, resz)
	Using the Legendre polynomials to find the rst coordinates on GPU.
subroutine	find_rst_legendre_cpu (this, rst, pt_x, pt_y, pt_z, el_list, n_pts, resx, resy, resz)
	Using the Legendre polynomials to find the rst coordinates.
