void libMesh::Elem::add_child ( Elem * elem )

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().

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.

◆ 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.

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.

Reimplemented from libMesh::InfPrism.

◆ 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.
