Active, local, and negation forms of the element iterators described above. An "active" element is an element without children (i.e. has not been refined). A "local" element is one whose processor_id() matches the current processor.

Add elem e
to the end of the element array. To add an element locally, set e->processor_id() before adding it. To ensure a specific element id, call e->set_id() before adding it; only do this in parallel if you are manually keeping ids consistent.
Users should call MeshBase::prepare_for_use() after elements are added to and/or deleted from the mesh.

Adds a functor which can specify ghosting requirements for use on distributed meshes. Multiple ghosting functors can be added; any element which is required by any functor will be ghosted.
GhostingFunctor memory must be managed by the code which calls this function; the GhostingFunctor lifetime is expected to extend until either the functor is removed or the Mesh is destructed.

Prepare to identify (and then delete) a bunch of no-longer-used nodes.

Converts a (conforming, non-refined) mesh with linear elements into a mesh with second-order elements. For example, a mesh consisting of Tet4
will be converted to a mesh with Tet10
etc.
Hex8
there exist two higher order equivalents, Hex20
and Hex27
. When full_ordered
is true
(default), then Hex27
is built. Otherwise, Hex20
is built. The same holds obviously for Quad4
, Prism6
, etc. Loop over the low-ordered elements in the elements vector. First make sure they _are indeed low-order, and then replace them with an equivalent second-order element. Don't forget to delete the low-order element, or else it will leak!
If the linear element had any boundary conditions they should be transferred to the second-order element. The old boundary conditions will be removed from the BoundaryInfo data structure by insert_elem.
Also, prepare_for_use() will reconstruct most of our neighbor links, but if we have any remote_elem links in a distributed mesh, they need to be preserved. We do that in the same loop here.

If false is passed in then this mesh will no longer have remote elements deleted when being prepared for use; i.e. even a DistributedMesh will remain (if it is already) serialized. This may adversely affect performance and memory use.

If false is passed in then this mesh will no longer be renumbered when being prepared for use. This may slightly adversely affect performance during subsequent element access, particularly when using a distributed mesh.
Important! When allow_renumbering(false) is set, ReplicatedMesh::n_elem() and ReplicatedMesh::n_nodes() will return wrong values whenever adaptive refinement is followed by adaptive coarsening. (Uniform refinement followed by uniform coarsening is OK.) This is due to the fact that n_elem() and n_nodes() are currently O(1) functions that just return the size of the respective underlying vectors, and this size is wrong when the numbering includes "gaps" from nodes and elements that have been deleted. We plan to implement a caching mechanism in the near future that will fix this incorrect behavior.

Other functions from MeshBase requiring re-definition.
Here we look at all of the child elements which don't already have valid neighbors.
If a child element has a nullptr neighbor it is either because it is on the boundary or because its neighbor is at a different level. In the latter case we must get the neighbor from the parent.
If a child element has a remote_elem neighbor on a boundary it shares with its parent, that info may have become out-dated through coarsening of the neighbor's parent. In this case, if the parent's neighbor is active then the child should share it.
Furthermore, that neighbor better be active, otherwise we missed a child somewhere.
We also need to look through children ordered by increasing refinement level in order to add new interior_parent() links in boundary elements which have just been generated by refinement, and fix links in boundary elements whose previous interior_parent() has just been coarsened away.

This function and others must be defined in derived classes since the MeshBase class has no specific storage for nodes or elements. The standard n_nodes()
function may return a cached value on distributed meshes, and so can be called by any processor at any time.

For example, a 9-noded quadrilateral will be broken into 4 linear sub-elements for plotting purposes. Thus, for a mesh of 2 QUAD9
elements n_tecplot_elem()
will return 8. Implemented in terms of element_iterators.
