Constructor & Destructor Documentation

◆ FroIO()

libMesh::FroIO::FroIO ( const MeshBase mesh_in)
explicit

Constructor.

Takes a reference to a constant mesh object. This constructor will only allow us to write the mesh.

Member Function Documentation

◆ ascii_precision()

unsigned int & libMesh::MeshOutput< MeshBase >::ascii_precision ( )
inherited

Return/set the precision to use when writing ASCII files.

By default we use numeric_limits<Real>::digits10 + 2, which should be enough to write out to ASCII and get the exact same Real back when reading in.

Definition at line 244 of file mesh_output.h.

245 {
246  return _ascii_precision;
247 }
unsigned int _ascii_precision
Precision to use when writing ASCII files.

◆ mesh()

const MeshBase & libMesh::MeshOutput< MeshBase >::mesh ( ) const
protectedinherited
Returns
The object as a read-only reference.

237  return *_obj;

const MeshBase *const _obj
A pointer to a constant object.

◆ write()

virtual void libMesh::FroIO::write ( const std::string &  )
overridevirtual

This method implements writing a mesh to a specified file.

Implements libMesh::MeshOutput< MeshBase >.

◆ write_discontinuous_equation_systems()

virtual void libMesh::MeshOutput< MeshBase >::write_discontinuous_equation_systems ( const std::string &  ,
const EquationSystems ,
const std::set< std::string > *  system_names = nullptr 
)
virtualinherited

This method implements writing a mesh with discontinuous data to a specified file where the data is taken from the EquationSystems object.

◆ write_equation_systems()

virtual void libMesh::MeshOutput< MeshBase >::write_equation_systems ( const std::string &  ,
const EquationSystems ,
const std::set< std::string > *  system_names = nullptr 
)
virtualinherited

This method implements writing a mesh with data to a specified file where the data is taken from the EquationSystems object.

Reimplemented in libMesh::NameBasedIO.

◆ write_nodal_data() [1/2]

virtual void libMesh::MeshOutput< MeshBase >::write_nodal_data ( const std::string &  ,
const std::vector< Number > &  ,
const std::vector< std::string > &   
)
virtualinherited

This method implements writing a mesh with nodal data to a specified file where the nodal data and variable names are provided.

Reimplemented in libMesh::ExodusII_IO, libMesh::Nemesis_IO, libMesh::UCDIO, libMesh::NameBasedIO, libMesh::GmshIO, libMesh::GMVIO, libMesh::VTKIO, libMesh::MEDITIO, libMesh::GnuPlotIO, and libMesh::TecplotIO.

◆ write_nodal_data() [2/2]

virtual void libMesh::MeshOutput< MeshBase >::write_nodal_data ( const std::string &  ,
const NumericVector< Number > &  ,
const std::vector< std::string > &   
)
virtualinherited

This method should be overridden by "parallel" output formats for writing nodal data.

Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.

If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.

Reimplemented in libMesh::Nemesis_IO.

◆ write_nodal_data_discontinuous()

virtual void libMesh::MeshOutput< MeshBase >::write_nodal_data_discontinuous ( const std::string &  ,
const std::vector< Number > &  ,
const std::vector< std::string > &   
)
virtualinherited

This method implements writing a mesh with discontinuous data to a specified file where the nodal data and variables names are provided.

Reimplemented in libMesh::ExodusII_IO.

Member Data Documentation

◆ _is_parallel_format

const bool libMesh::MeshOutput< MeshBase >::_is_parallel_format
protectedinherited

Flag specifying whether this format is parallel-capable.

If this is false (default) I/O is only permitted when the mesh has been serialized.

Definition at line 159 of file mesh_output.h.

◆ _serial_only_needed_on_proc_0

const bool libMesh::MeshOutput< MeshBase >::_serial_only_needed_on_proc_0
protectedinherited

Flag specifying whether this format can be written by only serializing the mesh to processor zero.

If this is false (default) the mesh will be serialized to all processors
