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 )

virtual

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.

overridevirtual

functions for adding /deleting nodes elements.

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.

allgather()

virtual void libMesh::DistributedMesh::allgather ( )

overridevirtual

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_noncritical_partitioning() [1/2]

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

inherited

If true is passed in then the elements on this mesh will no longer be (re)partitioned, and the nodes on this mesh will only be repartitioned if they are found "orphaned" via coarsening or other removal of the last element responsible for their node/element processor id consistency.

Note

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.

Skipping 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 noncritical partitioning by resetting the partitioner() pointer for this mesh.

skip_partitioning() [1/2]

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

inherited

If true is passed in then nothing on this mesh will be (re)partitioned.

Note

The caveats for skip_noncritical_partitioning() still apply, and removing elements from a mesh with this setting enabled can leave node processor ids in an inconsistent state (not matching any attached element), causing failures in other library code. Do not use this setting along with element deletion or coarsening.

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()
