Detailed Description

The DistributedMesh class is derived from the MeshBase class, and is intended to provide identical functionality to the user but be distributed rather than replicated across distributed-memory systems.

add_elem()

virtual Elem* libMesh::DistributedMesh::add_elem ( Elem *  e )

overridevirtual

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.

Implements libMesh::MeshBase.

add_extra_ghost_elem()

virtual void libMesh::DistributedMesh::add_extra_ghost_elem ( Elem *  e )

Inserts the element and adds it to a list of elements that should not get deleted or have their descendants deleted by delete_remote_elements.

This is handy for inserting otherwise off-processor elements that you want to keep track of on this processor.

add_ghosting_functor()

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

inherited

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.

Implements libMesh::MeshBase.

all_first_order()

virtual void libMesh::UnstructuredMesh::all_first_order ( )

overridevirtualinherited

Converts a mesh with higher-order elements into a mesh with linear elements.

For example, a mesh consisting of Tet10 will be converted to a mesh with Tet4 etc.

Implements libMesh::MeshBase.

all_second_order()

virtual void libMesh::UnstructuredMesh::all_second_order ( const bool  full_ordered = true )

overridevirtualinherited

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.

Implements libMesh::MeshBase.

Gathers all elements and nodes of the mesh onto every processor.

Reimplemented from libMesh::MeshBase.

allow_remote_element_removal() [1/2]

void libMesh::MeshBase::allow_remote_element_removal ( bool  allow )

inherited

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.

allow_renumbering() [1/2]

void libMesh::MeshBase::allow_renumbering ( bool  allow )

inherited

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.

skip_partitioning() [1/2]

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

inherited

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.

It is also possible, for backwards-compatibility purposes, to skip partitioning by resetting the partitioner() pointer for this mesh.

spatial_dimension()

unsigned int libMesh::MeshBase::spatial_dimension ( ) const

inherited

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.

sub_point_locator()

_count_lower_dim_elems_in_point_locator

bool libMesh::MeshBase::_count_lower_dim_elems_in_point_locator

Do we count lower dimensional elements in point locator refinement? This is relevant in tree-based point locators, for example.

Definition at line 1404 of file mesh_base.h.

_default_ghosting

std::unique_ptr<GhostingFunctor> libMesh::MeshBase::_default_ghosting

protectedinherited

The default geometric GhostingFunctor, used to implement standard libMesh element ghosting behavior.

We use a base class pointer here to avoid dragging in more header dependencies.

_elem_dims

std::set<unsigned char> libMesh::MeshBase::_elem_dims

We cache the dimension of the elements present in the mesh.

So, if we have a mesh with 1D and 2D elements, this structure will contain 1 and 2.

_extra_ghost_elems

std::set<Elem *> libMesh::DistributedMesh::_extra_ghost_elems

protected

These are extra ghost elements that we want to make sure not to delete when we call delete_remote_elements()

Definition at line 570 of file distributed_mesh.h.

Referenced by clear_extra_ghost_elems().

_ghosting_functors

std::set<GhostingFunctor *> libMesh::MeshBase::_ghosting_functors

protectedinherited

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.

_n_parts

unsigned int libMesh::MeshBase::_n_parts

protectedinherited

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.

_partitioner

std::unique_ptr<Partitioner> libMesh::MeshBase::_partitioner

protectedinherited

A partitioner to use at each prepare_for_use().

This will be built in the constructor of each derived class, but can be replaced by the user through the partitioner() accessor.

_point_locator

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

mutableprotectedinherited

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.

boundary_info

std::unique_ptr<BoundaryInfo> libMesh::MeshBase::boundary_info

inherited

This class holds the boundary information.

It can store nodes, edges, and faces with a corresponding id that facilitates setting boundary conditions.

Direct access to this class will be removed in future libMesh versions. Use the get_boundary_info() accessor instead.
