Detailed Description

Definition at line 35 of file msh_gmshreader.h.

Member Typedef Documentation

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 78 of file msh_gmshreader.h.

Constructor & Destructor Documentation

GmshMeshReader::GmshMeshReader

(

const FilePath &

file_name

)

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

Definition at line 38 of file msh_gmshreader.cc.

GmshMeshReader::~GmshMeshReader ( )

virtual

Destructor close the file if opened.

Definition at line 49 of file msh_gmshreader.cc.

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

overridevirtual

Finds GMSH data header for ElementData given by time and field_name and stores it as actual_header_.

Implements BaseMeshReader.

Definition at line 324 of file msh_gmshreader.cc.

void GmshMeshReader::make_header_table ( )

overrideprotectedvirtual

Reads table of ElementData headers from the tokenizer file.

Implements BaseMeshReader.

Definition at line 297 of file msh_gmshreader.cc.

Here is the caller graph for this function:

void GmshMeshReader::read_data_header ( MeshDataHeader &  head )

protected

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

Here is the caller graph for this function:

void GmshMeshReader::read_element_data ( ElementDataCacheBase &  data_cache, MeshDataHeader  actual_header, unsigned int  n_components, bool  boundary_domain  )

Implements BaseMeshReader::read_element_data.

Implements BaseMeshReader.

Definition at line 253 of file msh_gmshreader.cc.

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 88 of file msh_gmshreader.cc.

void GmshMeshReader::read_nodes ( Mesh *  mesh )

protectedvirtual

private method for reading of nodes

Implements BaseMeshReader.

Definition at line 54 of file msh_gmshreader.cc.

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.

Implements BaseMeshReader.
