◆ contains_edge_of()

virtual bool libMesh::Elem::contains_point	(	const Point &	p,

Returns: true if the point p is contained in this element, false otherwise.

For linear elements, performs an initial tight bounding box check (as an optimization step) and (if that passes) then uses the user-defined tolerance "tol" in a call to inverse_map() to actually test if the point is in the element. For quadratic elements, the bounding box optimization is skipped, and only the inverse_map() steps are performed.

Note: This routine should not be used to determine if a point is merely "nearby" an element to within some tolerance. For that, use Elem::close_to_point() instead.

◆ family_tree()

void libMesh::Elem::family_tree	(	std::vector< const Elem *> &	family,
		const bool	reset = `true`
	)		const

inherited

Fills the vector family with the children of this element, recursively.

Calling this method on a twice-refined element will give you the element itself, its direct children, and their children, etc... When the optional parameter reset is true, the vector will be cleared before the element and its descendants are added.

The family tree only includes ancestor and active elements. To include subactive elements as well, use total_family_tree().

◆ family_tree_by_neighbor()

void libMesh::Elem::family_tree_by_neighbor	(	std::vector< const Elem *> &	family,
		const Elem *	neighbor,
		const bool	reset = `true`
	)		const

Same as the family_tree() member, but only adds elements which are next to neighbor.

void libMesh::Elem::family_tree_by_side	(	std::vector< const Elem *> &	family,
		const unsigned int	side,

		const Elem *	neighbor,
		const Elem *	subneighbor,

Same as the family_tree() member, but only adds elements which are next to subneighbor.

Only applicable when this->has_neighbor(neighbor) and neighbor->is_ancestor(subneighbor)

void libMesh::Elem::find_edge_neighbors	(	const Point &	p1,

In this case, elements are included even if they do not touch a whole edge of this element.

◆ find_interior_neighbors()

This function finds all active elements (not including this one) in the parent manifold of this element whose intersection with this element has non-zero measure.

◆ find_point_neighbors() [1/3]

void libMesh::Elem::find_point_neighbors	(	const Point &	p,

	)		const

inherited

This function finds all active elements (including this one) which are in the same manifold as this element and which touch the current active element at the specified point, which should be a point in the current element.

Elements which are not "in the same manifold" (e.g. the interior_parent of a boundary element) will not be found with this method.

Elements which overlap the specified point but which are only connected to the current element via elements which do not overlap that point (e.g. in a folded or tangled mesh) are not considered to "touch" the current element and will not be found with this method.

◆ find_point_neighbors() [2/3]

◆ interior_parent() [1/2]

Returns: The higher-dimensional Elem for which this Elem is a face.

In some cases it is desirable to extract the boundary (or a subset thereof) of a D-dimensional mesh as a (D-1)-dimensional manifold. In this case we may want to know the 'parent' element from which the manifold elements were extracted. We can easily do that for the level-0 manifold elements by storing the D-dimensional parent. This method provides access to that element.

This method is not safe to call if this->dim() == LIBMESH_DIM; in such cases no data storage for an interior parent pointer has been allocated.

A remote element (see RemoteElem) is a syntactic convenience – it is a placeholder for an element which exists on some other processor. Local elements are required to have valid neighbors, and these ghost elements may have remote neighbors for data structure consistency. The use of remote elements helps ensure that any element we may access has a nullptr neighbor only if it lies on the physical boundary of the domain.

Returns: The element type of the associated second-order element, or INVALID_ELEM for second-order or other elements that cannot be converted into higher order equivalents.

For example, when this is a TET4, then TET10 is returned.

For some elements, there exist two second-order equivalents, e.g. for Quad4 there is Quad8 and Quad9. When the optional full_ordered is true, then QUAD9 is returned. When full_ordered is false, then QUAD8 is returned.

◆ which_node_am_i()

Returns: side after doing some range checking. side_node is ignored.

Implements libMesh::Elem.

◆ which_side_am_i()

unsigned int libMesh::Elem::which_side_am_i ( const Elem * e ) const

inherited

This function tells you which side the boundary element e is.

I.e. if e = a->build_side_ptr(s) or e = a->side_ptr(s); then a->which_side_am_i(e) will be s.

Note: An exact floating point comparison of the nodal positions of e is made with the nodal positions of this in order to perform this test. The idea is that the test will return a valid side id if e either directly shares Node pointers with this, or was created by exactly copying some of the nodes of this (e.g. through BoundaryMesh::sync()). In these circumstances, non-fuzzy floating point equality is expected.

Returns: The side of this the element which e is, otherwise invalid_uint.
