Detailed Description

Base class for Mesh.

This is the MeshBase class. This class provides all the data necessary to describe a geometric entity. It allows for the description of a dim dimensional object that lives in LIBMESH_DIM-dimensional space.

A mesh is made of nodes and elements, and this class provides data structures to store and access both. A mesh may be partitioned into a number of subdomains, and this class provides that functionality. Furthermore, this class provides functions for reading and writing a mesh to disk in various formats.

Constructor & Destructor Documentation

libMesh::MeshBase::MeshBase ( const Parallel::Communicator comm_in,
unsigned char  dim = 1 
)

Constructor. Takes dim, the dimension of the mesh. The mesh dimension can be changed (and may automatically be changed by mesh generation/loading) later.

libMesh::MeshBase::MeshBase ( unsigned char  dim = 1)

Constructor which takes dim, the dimension of the mesh. The mesh dimension can be changed (and may automatically be changed by mesh generation/loading) later.

Deprecated:
LIBMESH_DISABLE_COMMWORLD is now the default, use the constructor that takes a Parallel::Communicator instead.

void libMesh::MeshBase::add_ghosting_functor ( GhostingFunctor ghosting_functor)
inline

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.

const dof_id_type  id = DofObject::invalid_id,
const processor_id_type  proc_id = DofObject::invalid_processor_id

pure virtual

Add a new Node at Point p to the end of the vertex array, with processor_id procid. Use DofObject::invalid_processor_id (default) to add a node to all processors, or this->processor_id() to add a node to the local processor only. If adding a node locally, passing an id other than DofObject::invalid_id will set that specific node id. Only do this in parallel if you are manually keeping ids consistent.

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.

Note
For some elements like 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.

Delete subactive (i.e. children of coarsened) elements. This removes all elements descended from currently active elements in the mesh.

Implemented in libMesh::UnstructuredMesh.

Referenced by query_elem(), and libMesh::EquationSystems::reinit_solutions().

virtual void libMesh::MeshBase::delete_elem ( Elem e)
pure virtual

Removes element e from the mesh. This method must be implemented in derived classes in such a way that it does not invalidate element iterators. Users should call MeshBase::prepare_for_use() after elements are added to and/or deleted from the mesh.

Note
Calling this method may produce isolated nodes, i.e. nodes not connected to any element.

Locate element face (edge in 2D) neighbors. This is done with the help of a std::map that functions like a hash table. After this routine is called all the elements with a NULL neighbor pointer are guaranteed to be on the boundary. Thus this routine is useful for automatically determining the boundaries of the domain. If reset_remote_elements is left to false, remote neighbor links are not reset and searched for in the local mesh. If reset_current_list is left as true, then any existing links will be reset before initiating the algorithm, while honoring the value of the reset_remote_elements flag.

void libMesh::MeshBase::prepare_for_use ( const bool  skip_renumber_nodes_and_elements = false,

Prepare a newly created (or read) mesh for use. This involves 4 steps: 1.) call find_neighbors() 2.) call partition() 3.) call renumber_nodes_and_elements() 4.) call cache_elem_dims()

The argument to skip renumbering is now deprecated - to prevent a mesh from being renumbered, set allow_renumbering(false).

If this is a distributed mesh, local copies of remote elements will be deleted here - to keep those elements replicated during preparation, set allow_remote_element_removal(false).

In a few (very rare) cases, the user may have manually tagged the elements with specific processor IDs by hand, without using a partitioner. In this case, the Mesh will not know that the total number of partitions, _n_parts, has changed, unless you call this function. This is an O(N active elements) calculation. The return value is the number of partitions, and _n_parts is also set by this function.

void libMesh::MeshBase::skip_partitioning ( bool  skip)
inline

If true is passed in then this mesh will no longer be (re)partitioned. It would probably be a bad idea to call this on a DistributedMesh before the first partitioning has happened... because no elements would get assigned to your processor pool.

Note
Turning on skip_partitioning() can have adverse effects on your performance when using AMR... i.e. you could get large load imbalances. However you might still want to use this if the communication and computation of the rebalance and repartition is too high for your application.

unsigned int libMesh::MeshBase::spatial_dimension ( ) const
Returns
The "spatial dimension" of the mesh.

The spatial dimension is defined as:

1 - for an exactly x-aligned mesh of 1D elements 2 - for an exactly x-y planar mesh of 2D elements 3 - otherwise

No tolerance checks are performed to determine whether the Mesh is x-aligned or x-y planar, only strict equality with zero in the higher dimensions is checked. Also, x-z and y-z planar meshes are considered to have spatial dimension == 3.

The spatial dimension is updated during prepare_for_use() based on the dimensions of the various elements present in the Mesh, but is never automatically decreased by this function.

For example, if the user calls set_spatial_dimension(2) and then later inserts 3D elements into the mesh, Mesh::spatial_dimension() will return 3 after the next call to prepare_for_use(). On the other hand, if the user calls set_spatial_dimension(3) and then inserts only x-aligned 1D elements into the Mesh, mesh.spatial_dimension() will remain 3.

void libMesh::MeshBase::subdomain_ids ( std::set< subdomain_id_type > &  ids) const

Constructs a list of all subdomain identifiers in the global mesh. Subdomains correspond to separate subsets of the mesh which could correspond e.g. to different materials in a solid mechanics application, or regions where different physical processes are important. The subdomain mapping is independent from the parallel decomposition.

The list of all GhostingFunctor objects to be used when distributing a DistributedMesh.

Basically unused by ReplicatedMesh for now, but belongs to MeshBase because the cost is trivial.

unsigned int libMesh::MeshBase::_n_parts
protected

The number of partitions the mesh has. This is set by the partitioners, and may not be changed directly by the user.

Note
The number of partitions need not equal this->n_processors(), consider for example the case where you simply want to partition a mesh on one processor and view the result in GMV.

std::unique_ptr<PointLocatorBase> libMesh::MeshBase::_point_locator
mutableprotected

A PointLocator class for this mesh. This will not actually be built unless needed. Further, since we want our point_locator() method to be const (yet do the dynamic allocating) this needs to be mutable. Since the PointLocatorBase::build() member is used, and it operates on a constant reference to the mesh, this is OK.
