Detailed Description

A concrete mesh class for libMesh.

This class provides routines for reading, accessing and writing libMesh meshes. The generation of the mesh is controlled by the database passed in through the params object. The database fields control the mesh and provide several options:

   dim - required integer specifying the physical dimension
   FileName - If specified this will load the mesh from the given file
   Generator - If specified this will generate a new mesh using the optional parameters in the
database
      This field must be a string specifying the generator to use.  Valid gerators are:
         "cube" - Will generate a cube mesh
      Additional areguments:
         size - Integer array specifying the number of elements in each direction

The parallel decomposition of the mesh is controlled by libmesh and occurs on the communicator specified through the params object. Note that libmesh does not support meshes on overlapping communicators. If multiple meshes are used, they must either share communicators or have unique communicators.

Constructor & Destructor Documentation

◆ libmeshMesh() [1/3]

AMP::Mesh::libmeshMesh::libmeshMesh ( std::shared_ptr< const MeshParameters > params )

explicit

Read in mesh files, partition domain, and prepare environment for simulation.

For trivial parallelsim, this method reads in the meshes on each processor. Each processor contains a piece of each mesh. For massive parallelism, each mesh is on its own communicator. As such, some math libraries must be initialized accordingly.

Parameters

params Parameters for constructing a mesh from an input database

◆ libmeshMesh() [2/3]

AMP::Mesh::libmeshMesh::libmeshMesh	(	std::shared_ptr< libMesh::Mesh >	mesh,
		const std::string &	name,
		std::shared_ptr< libMesh::Parallel::Communicator >	libMeshComm = `nullptr`
	)

explicit

Constructor to create a libmeshMesh object from a libMesh mesh.

This constructor allows the user to construct a mesh directly in libmesh and use it to create the new mesh object. This function is intended for advanced users only. Note: the user is responsible for ensuring that libMesh is properly initialized (using initializeLibMesh), and that the mesh is created properly.

Parameters

mesh	The mesh in libmesh we want to use to construct the new mesh object
name	The name of the new mesh object
libMeshComm	Optional libMesh communicator to use

◆ ~libmeshMesh()

virtual AMP::Mesh::libmeshMesh::~libmeshMesh ( )

◆ setMeshID()

void AMP::Mesh::Mesh::setMeshID ( )

protectedinherited

A function to create a unique id for the mesh (requires the comm to be set) Note: this requires a global communication across the mesh communicator. Note: this function is NOT thread safe, and will need to be modified before threads are used.

◆ setName()

virtual void AMP::Mesh::Mesh::setName ( std::string name )

inlinevirtualinherited

Set the mesh name.

◆ Subset() [1/4]

virtual std::shared_ptr< Mesh > AMP::Mesh::Mesh::Subset	(	const MeshIterator &	iterator,
		bool	isGlobal = `true`
	)		const

virtualinherited

Subset a mesh given a MeshIterator.

This function will subset a mesh over a given iterator. This will return a new mesh object.

Parameters

iterator	MeshIterator used to subset
isGlobal	Is the new subset mesh global over the entire mesh (true,default), or do we only want to keep the local mesh (false)

Reimplemented in AMP::Mesh::MultiMesh, AMP::Mesh::SubsetMesh, and AMP::Mesh::MultiMesh.

◆ Subset() [2/4]

virtual std::shared_ptr< Mesh > AMP::Mesh::Mesh::Subset ( Mesh & mesh ) const

virtualinherited

Subset a mesh given another mesh.

This function will subset a mesh given another mesh

Parameters

mesh	Mesh used to subset

Reimplemented in AMP::Mesh::MultiMesh, and AMP::Mesh::SubsetMesh.

◆ Subset() [3/4]

virtual std::shared_ptr< Mesh > AMP::Mesh::Mesh::Subset ( MeshID meshID ) const

virtualinherited

Subset a mesh given a MeshID.

This function will return the mesh with the given meshID. Note: for multimeshes, this will return the mesh with the given id. For a single mesh this will return a pointer to itself if the meshID matches the meshID of the mesh, and a null pointer otherwise.

Parameters

meshID MeshID of the desired mesh

Reimplemented in AMP::Mesh::MultiMesh, AMP::Mesh::SubsetMesh, AMP::Mesh::MultiMesh, and AMP::Mesh::SubsetMesh.

◆ Subset() [4/4]

virtual std::shared_ptr< Mesh > AMP::Mesh::Mesh::Subset ( std::string name ) const

virtualinherited

Subset a mesh given a mesh name.

This function will return the mesh with the given name. For a single mesh this will return a pointer to itself if the mesh name matches the name of the mesh, and a null pointer otherwise. Note: The mesh name is not guaranteed to be unique. If there are multiple meshes with the same name, all meshed with the given name will be returned within a new multimesh. It is strongly recommended to use the meshID when possible.

Parameters

name	Name of the desired mesh

Reimplemented in AMP::Mesh::MultiMesh, AMP::Mesh::SubsetMesh, AMP::Mesh::MultiMesh, and AMP::Mesh::SubsetMesh.

◆ writeRestart()

void AMP::Mesh::libmeshMesh::writeRestart ( int64_t fid ) const

overridevirtual

Write restart data to file.

This function will write the mesh to an HDF5 file

Parameters

fid	File identifier to write

Reimplemented from AMP::Mesh::Mesh.
