	)

Initialize the field-aligned mapping between adjacent planes. The routine traces magnetic field lines from each vertex of a plane in both toroidal directions to the adjacent mid-planes and full-step planes, records the triangle in which the field line intersects these planes and the corresponding interpolation weights.

Parameters

[in]	plane_start	the plane being projected from
[in]	plane_dest	the plane being projected to
[in]	magnetic_field	the magnetic field for field following
[in]	tr_node	the triangle-to-node mapping of the destination plane
[in]	weight_p_on_boundary	whether to weight the nearest node if the projection falls outside the grid
[out]	tr_d	the triangles on the destination plane
[out]	nd_d	the nodes on the destination plane
[out]	p_d	the barycentric weights on the destination plane
[out]	dx_d	distance traveled along the field line
[in]	use_two_step_method	whether to use an intermediate value to increase accuracy of dx

use_nearest_triangle()

KOKKOS_INLINE_FUNCTION void use_nearest_triangle	(	const Plane< DeviceType > &	plane,
		const View< int **, CLayout, DeviceType > &	tr_node,
		const SimdVector2D &	x,
		bool	weight_p_on_boundary,
		int	i_simd,
		Simd< int > &	itr,
		SimdGridVec &	p_loc
	)

Find the nearest triangle and use it. This algorithm loops over ALL nodes - very inefficient! Should use wall nodes - or last surface if no wall is present

Parameters

[in]	plane	the plane
[in]	tr_node	the triangle-to-node mapping of the plane
[in]	x	the coordinates on the plane
[in]	weight_p_on_boundary	whether to weight the nearest node if the projection falls outside the grid
[in]	i_simd	the simd index since this is a vectorized operation
[out]	itr	the index of the nearest triangle
[out]	p_loc	the barycentric weights on the nearest triangle
