Member Typedef Documentation

◆ HeaderTable

typedef std::map< std::string, std::vector<MeshDataHeader> > GmshMeshReader::HeaderTable

protected

Map of ElementData sections in GMSH file.

For each field_name contains vector of MeshDataHeader. Headers are sorted by time in ascending order.

Definition at line 85 of file msh_gmshreader.h.

Constructor & Destructor Documentation

◆ GmshMeshReader()

GmshMeshReader::GmshMeshReader ( const FilePath & file_name )

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

Definition at line 39 of file msh_gmshreader.cc.

◆ ~GmshMeshReader()

GmshMeshReader::~GmshMeshReader ( )

virtual

Destructor close the file if opened.

◆ find_header()

BaseMeshReader::MeshDataHeader & GmshMeshReader::find_header ( BaseMeshReader::HeaderQuery & header_query )

overridevirtual

Finds GMSH data header for ElementData given by time and field_name.

Implements BaseMeshReader.

Definition at line 334 of file msh_gmshreader.cc.

◆ make_header_table()

void GmshMeshReader::make_header_table ( )

overrideprotectedvirtual

Reads table of ElementData headers from the tokenizer file.

Implements BaseMeshReader.

Definition at line 307 of file msh_gmshreader.cc.

Here is the caller graph for this function:

◆ read_data_header()

void GmshMeshReader::read_data_header ( MeshDataHeader & head )

protected

Reads the header from the tokenizer tok and return it as the second parameter.

Definition at line 195 of file msh_gmshreader.cc.

◆ read_element_data()

void GmshMeshReader::read_element_data	(	ElementDataCacheBase &	data_cache,

	)

overrideprotectedvirtual

Implements BaseMeshReader::read_element_data.

Implements BaseMeshReader.

Definition at line 252 of file msh_gmshreader.cc.

◆ read_elements()

void GmshMeshReader::read_elements ( Mesh * mesh )

protectedvirtual

Method for reading of elements. Input of the mesh allows changing regions within the input CON file. Read section '$PhysicalNames' of the GMSH file and save the physical sections to general data structure.

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 89 of file msh_gmshreader.cc.

◆ read_nodes()

void GmshMeshReader::read_nodes ( Mesh * mesh )

protectedvirtual

private method for reading of nodes

Implements BaseMeshReader.

Definition at line 55 of file msh_gmshreader.cc.

◆ read_physical_names()

void GmshMeshReader::read_physical_names ( Mesh * mesh )

overridevirtual

Read section '$PhysicalNames' of the GMSH 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.
