◆ find_header()

virtual MeshDataHeader& BaseMeshReader::find_header ( HeaderQuery header_query)
pure virtual

Find data header for time and field given by header_query.

Implemented in VtkMeshReader, PvdMeshReader, and GmshMeshReader.

◆ get_element_data()

template<typename T >
ElementDataCache< T >::CacheData BaseMeshReader::get_element_data ( MeshDataHeader  header,
unsigned int  expected_n_entities,
unsigned int  expected_n_components,
unsigned int  boundary_begin 
)

Reads ElementData sections of opened mesh file. Method must be call after set_data_header method. If such section has not been yet read, we read the data section into raw buffer data. The buffer must have size at least n_components * n_entities. Indexes in the map must be smaller then n_entities.

Possible optimizations: If the map ID lookup seem slow, we may assume that IDs are in increasing order, use simple array of IDs instead of map and just check that they comes in in correct order.

Parameters
n_entitiescount of entities (elements)
n_componentscount of components (size of returned data is given by n_entities*n_components)
boundary_domainflag determines that data is read for boundary or bulk elements
component_idxcomponent index of MultiField; 0 for single component fields.

Definition at line 95 of file msh_basereader.cc.

◆ get_element_ids()

std::vector< int > const & BaseMeshReader::get_element_ids ( bool  boundary_domain)

Returns vector of boundary or bulk element IDs to read. Used by GMSH reader only.
