Detailed Description

Constructor & Destructor Documentation

◆ PvdMeshReader()

PvdMeshReader::PvdMeshReader ( const FilePath file_name)

Construct the PVD reader from given FilePath. This opens the file for reading.

Definition at line 29 of file msh_pvdreader.cc.

◆ ~PvdMeshReader()

PvdMeshReader::~PvdMeshReader ( )

Destructor.

Definition at line 39 of file msh_pvdreader.cc.

Member Function Documentation

◆ find_header()

BaseMeshReader::MeshDataHeader & PvdMeshReader::find_header ( BaseMeshReader::HeaderQuery header_query)
overridevirtual

Find header of DataArray section of VTK file given by field_name.

Implements BaseMeshReader.

Definition at line 94 of file msh_pvdreader.cc.

◆ make_header_table()

void PvdMeshReader::make_header_table ( )
overrideprotectedvirtual

This method is specified for PVD reader. Table of mesh data headers (same as for GMSH or VTK) is not created, but list of times and appropriate VTK files is filled.

Implements BaseMeshReader.

Definition at line 69 of file msh_pvdreader.cc.

Here is the caller graph for this function:

◆ read_element_data()

void PvdMeshReader::read_element_data ( ElementDataCacheBase data_cache,
MeshDataHeader  header 
)
overrideprotectedvirtual

Implements BaseMeshReader::read_element_data.

Implements BaseMeshReader.

Definition at line 64 of file msh_pvdreader.cc.

◆ read_elements()

void PvdMeshReader::read_elements ( Mesh mesh)
overrideprotectedvirtual

Method for reading of elements. Input of the mesh allows changing regions within the input file.

Implements BaseMeshReader.

Definition at line 59 of file msh_pvdreader.cc.

◆ read_nodes()

void PvdMeshReader::read_nodes ( Mesh mesh)
overrideprotectedvirtual

private method for reading of nodes

Implements BaseMeshReader.

Definition at line 53 of file msh_pvdreader.cc.

◆ read_physical_names()

void PvdMeshReader::read_physical_names ( Mesh mesh)
overridevirtual

Read regions from the VTK file and save the physical sections as regions in the RegionDB.

Region Labels starting with '!' are treated as boundary regions. Elements of these regions are used just to assign regions to the boundary and are not used in actual FEM computations.

Implements BaseMeshReader.

Definition at line 47 of file msh_pvdreader.cc.

Member Data Documentation

◆ file_list_

std::vector<VtkFileData> PvdMeshReader::file_list_
protected

Store list of VTK files and time steps declared in PVD file.

Definition at line 90 of file msh_pvdreader.hh.

◆ list_it_

std::vector<VtkFileData>::iterator PvdMeshReader::list_it_
protected

Iterator to items of file_list_.

Definition at line 96 of file msh_pvdreader.hh.

◆ pvd_path_dir_

std::string PvdMeshReader::pvd_path_dir_
protected

Path to PVD file allows construct FilePath objects of VTK files.

Definition at line 93 of file msh_pvdreader.hh.
