Detailed Description

The ReplicatedMesh class is derived from the MeshBase class, and is used to store identical copies of a full mesh data structure on each processor.

Most methods for this class are found in MeshBase, and most implementation details are found in UnstructuredMesh.

◆ add_elem()

virtual Elem* libMesh::ReplicatedMesh::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.

◆ add_ghosting_functor()

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.

◆ all_first_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.

◆ 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.

Reads the file specified by name.

Attempts to figure out the proper method by the file extension. This is now the only way to read a mesh. The UnstructuredMesh then initializes its data structures and is ready for use.

The skip_renumber_nodes_and_elements argument is now deprecated - to disallow renumbering, set MeshBase::allow_renumbering(false).

Set skip_find_neighbors=true to skip the find-neighbors operation during prepare_for_use. This operation isn't always necessary and it can be time-consuming, which is why we provide an option to skip it.

◆ recalculate_n_partitions()

unsigned int libMesh::MeshBase::recalculate_n_partitions ( )
inherited

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.

◆ redistribute()

Redistribute elements between processors.

This gets called automatically by the Partitioner, and is a no-op in the case of a ReplicatedMesh or serialized DistributedMesh

◆ 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.

◆ stitch_meshes()

void libMesh::ReplicatedMesh::stitch_meshes ( const ReplicatedMesh &  other_mesh,
boundary_id_type  this_mesh_boundary,
boundary_id_type  other_mesh_boundary,
Real  tol = TOLERANCE,
bool  clear_stitched_boundary_ids = false,
bool  verbose = true,
bool  use_binary_search = true,
bool  enforce_all_nodes_match_on_boundaries = false 
)

Stitch other_mesh to this mesh so that this mesh is the union of the two meshes.

this_mesh_boundary and other_mesh_boundary are used to specify a dim-1 dimensional surface on which we seek to merge any "overlapping" nodes, where we use the parameter tol as a relative tolerance (relative to the smallest edge length on the surfaces being stitched) to determine whether or not nodes are overlapping. If clear_stitched_boundary_ids==true, this function clears boundary_info IDs in this mesh associated this_mesh_boundary and other_mesh_boundary. If use_binary_search is true, we use an optimized "sort then binary search" algorithm for finding matching nodes. Otherwise we use a N^2 algorithm (which can be more reliable at dealing with slightly misaligned meshes). If enforce_all_nodes_match_on_boundaries is true, we throw an error if the number of nodes on the specified boundaries don't match the number of nodes that were merged. This is a helpful error check in some cases. If skip_find_neighbors is true, a faster stitching method is used, where the lists of neighbors for each elements are copied as well and patched, without calling the time-consuming find_neighbors() function.

Note that the element IDs for elements in the stitched mesh corresponding to "this" mesh will be unchanged. The IDs for elements corresponding to other_mesh will be incremented by this->max_elem_id().

There is no simple a priori relationship between node IDs in "this" mesh and other_mesh and node IDs in the stitched mesh because the number of nodes (and hence the node IDs) in the stitched mesh depend on how many nodes are stitched.

◆ stitch_surfaces()

void libMesh::ReplicatedMesh::stitch_surfaces ( boundary_id_type  boundary_id_1,
boundary_id_type  boundary_id_2,
Real  tol = TOLERANCE,
bool  clear_stitched_boundary_ids = false,
bool  verbose = true,

Similar to stitch_meshes, except that we stitch two adjacent surfaces within this mesh.
