Detailed Description

Definition at line 37 of file msh_gmshreader.h.

Member Typedef Documentation

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 55 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 37 of file msh_gmshreader.cc.

GmshMeshReader::~GmshMeshReader ( )
virtual

Destructor close the file if opened.

Definition at line 48 of file msh_gmshreader.cc.

Member Function Documentation

void GmshMeshReader::check_compatible_mesh ( Mesh mesh)
overridevirtual

Empty method for GMSH reader now.

Implements BaseMeshReader::check_compatible_mesh.

Implements BaseMeshReader.

)
MeshDataHeader & GmshMeshReader::find_header ( double  time,
std::string  field_name 
)
overrideprotectedvirtual

Finds GMSH data header for ElementData given by time and field_name and return it as the first parameter.

Implements BaseMeshReader.

Definition at line 323 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 296 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.

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

Implements BaseMeshReader::read_element_data.

Implements BaseMeshReader.

Definition at line 252 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 87 of file msh_gmshreader.cc.

void GmshMeshReader::read_nodes ( Mesh mesh)
protectedvirtual

private method for reading of nodes

Implements BaseMeshReader.

Definition at line 53 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.
