◆ build_side_ptr() [1/4]

virtual std::unique_ptr<Elem> libMesh::Elem::build_side_ptr ( const unsigned int  i,
bool  proxy = true 
)
pure virtualinherited
Returns
An element coincident with side i wrapped in a smart pointer.

The element returned is full-ordered, in contrast to the side method. For example, calling build_side_ptr(0) on a 20-noded hex will build a 8-noded quadrilateral coincident with face 0 and pass back the pointer. A std::unique_ptr<Elem> is returned to prevent a memory leak. This way the user need not remember to delete the object.

The second argument, which is true by default, specifies that a "proxy" element (of type Side) will be returned. This type of value is useful because it does not allocate additional memory, and is usually sufficient for FE calculation purposes. If you really need a full-ordered, non-proxy side object, call this function with proxy=false.

The const version of this function is non-virtual; it simply calls the virtual non-const version and const_casts the return type.

Resets the loose element side, which may currently point to a different side than i or even a different element than this, to point to side i on this. If side is currently an element of the wrong type, it will be freed and a new element allocated; otherwise no memory allocation will occur.

This should not be called with proxy Side elements. This will cause side to be a full-ordered element, even if it is handed a lower-ordered element that must be replaced.

The const version of this function is non-virtual; it simply calls the virtual non-const version and const_casts the return type.

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()

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().

◆ 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.

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.

◆ is_remote()

virtual bool libMesh::Elem::is_remote ( ) const
inlinevirtualinherited
Returns
true if this element is remote, false otherwise.

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.

◆ second_order_adjacent_vertex()

unsigned short int libMesh::Elem::second_order_adjacent_vertex ( const unsigned int  n,

virtualinherited
Returns
The element-local number of the $ v^{th} $ vertex that defines the $ n^{th} $ second-order node, or 0 for linear elements.
Note
The value is always less than this->n_vertices(), while n has to be greater than or equal to this->n_vertices().

Reimplemented in libMesh::InfHex18, libMesh::Pyramid14, libMesh::Hex27, libMesh::Prism18, libMesh::InfHex16, libMesh::Hex20, libMesh::Prism15, libMesh::Tet10, libMesh::Pyramid13, libMesh::Quad9, libMesh::Tri6, libMesh::InfPrism12, libMesh::Quad8, libMesh::InfQuad6, libMesh::Edge3, and libMesh::Edge4.

◆ second_order_child_vertex()

std::pair< unsigned short int, unsigned short int > libMesh::Elem::second_order_child_vertex ( const unsigned int  n) const
virtualinherited
Returns
A pair (c,v), where c == child index, and v == element-local index of the $ n^{th} $ second-order node on the parent element. For linear elements, (0,0) is returned.
Note
The return values are always less than this->n_children() and this->child_ptr(c)->n_vertices().
n has to be greater than or equal to this->n_vertices().
On refined second-order elements, the return value will satisfy this->node_ptr(n) == this->child_ptr(c)->node_ptr(v).

◆ second_order_equivalent_type()

ElemType libMesh::Elem::second_order_equivalent_type ( const ElemType  et,
const bool  full_ordered = true 
)
staticinherited
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.

◆ side_ptr() [1/4]

virtual std::unique_ptr<Elem> libMesh::Elem::side_ptr ( unsigned int  i)
pure virtualinherited
Returns
A proxy element coincident with side i.
Note
This method returns the minimum element necessary to uniquely identify the side. For example, the side of a hexahedron is always returned as a 4-noded quadrilateral, regardless of what type of hex you are dealing with. If you want the full-ordered face (i.e. a 9-noded quad face for a 27-noded hexahedron) use the build_side method.
The const version of this function is non-virtual; it simply calls the virtual non-const version and const_casts the return type.

Implemented in libMesh::RemoteElem, libMesh::InfQuad, libMesh::Quad, libMesh::InfHex, libMesh::InfPrism, libMesh::Edge, libMesh::Tri, libMesh::Hex, libMesh::Pyramid, libMesh::Prism, libMesh::NodeElem, and libMesh::Tet.

◆ side_ptr() [3/4]

virtual void libMesh::Elem::side_ptr ( std::unique_ptr< Elem > &  side,

)
pure virtualinherited

Resets the loose element side, which may currently point to a different side than i or even a different element than this, to point to side i on this. If side is currently an element of the wrong type, it will be freed and a new element allocated; otherwise no memory allocation will occur.

This should not be called with proxy Side elements. This will cause side to be a minimum-ordered element, even if it is handed a higher-ordered element that must be replaced.

The const version of this function is non-virtual; it simply calls the virtual non-const version and const_casts the return type.

◆ which_node_am_i()

virtual unsigned int libMesh::Elem::which_node_am_i ( unsigned int  side,
unsigned int  side_node 
) const
pure virtualinherited
Returns
The local node id for node side_node on side side of this Elem. Simply relies on the side_nodes_map for each of the derived types. For example, Tri3::which_node_am_i(0, 0) -> 0 Tri3::which_node_am_i(0, 1) -> 1 Tri3::which_node_am_i(1, 0) -> 1 Tri3::which_node_am_i(1, 1) -> 2 etc...

◆ which_side_am_i()

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

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.

Note
We don't use the static_cast(-1) trick here since subdomain_id_type is sometimes a signed integer for compatibility reasons (see libmesh/id_types.h).
Normally you can declare static const integral types directly in the header file (C++ standard, 9.4.2/4) but std::numeric_limits<T>::max() is not considered a "constant expression". This one is therefore defined in elem.C. http://stackoverflow.com/questions/2738435/using-numeric-limitsmax-in-constant-expressions
