template<typename T >

KOKKOS_FUNCTION EdgeElement< T >::point_t ippl::EdgeElement< T >::globalToLocal	(	const vertex_points_t &	global_vertices,
		const point_t &	point
	)		const

Transforms a point from global to local coordinates.

Parameters

global_vertices	A vector of the vertex indices of the global element to transform to in the mesh.
point	A point in global coordinates with respect to the global element.

point

)

const

Returns whether a point in local coordinates ([0, 1]) is inside the reference element.

Parameters

point

A point in local coordinates with respect to the reference element.

Returns

boolean - Returns true when the point is inside the reference element or on the boundary. Returns false else

localToGlobal()

template<typename T >

KOKKOS_FUNCTION EdgeElement< T >::point_t ippl::EdgeElement< T >::localToGlobal	(	const vertex_points_t &	global_vertices,

Parameters

global_vertices	A vector of the vertex indices of the global element to transform to in the mesh.
point	A point in local coordinates with respect to the reference element.

Equivalent to transforming a local point \(\hat{\boldsymbol{x}}\) on the local element \(\hat{K}\) to a point in the global coordinate system \(\boldsymbol{x}\) on \(K\) by applying the transformation \(\mathbf{\Phi}_K\)

\[\boldsymbol{x} = \mathbf{\Phi}_K(\hat{\boldsymbol{x}})\]

Returns

point_t
