Detailed Description

Custom mesh/data absorber for unstructured grids given by external files *.vtu.

Read unstructured mesh data only from an external file vtu (any other data will be skipped). Data will be stored in internal structures of the streamer.

absorbData()

void mimmo::VTUGridStreamer::absorbData ( std::fstream &  stream, const std::string &  name, bitpit::VTKFormat  format, uint64_t  entries, uint8_t  components, bitpit::VTKDataType  datatype  )

virtual

Absorber of VTU mesh data. Reimplemented from bitpit::VTKBaseStreamer class

Parameters

[in]	stream	stream to read from
[in]	name	name of the geometry field
[in]	format	ASCII or APPENDED
[in]	entries	number of entries for data container
[in]	components	number of components of current data container
[in]	datatype	data format for binary casting

Reimplemented from mimmo::VTUAbsorbStreamer.

Definition at line 74 of file VTUGridReader.cpp.

decodeRawData()

void mimmo::VTUGridStreamer::decodeRawData ( bitpit::PatchKernel &  patch )

virtual

Use streamer absorbed data, if any, to fill vertices and cells info of target bitpit::PatchKernel container, passed externally. Please notice, container must be empty.

Parameters

[in]

patch

container for mesh

Implements mimmo::VTUAbsorbStreamer.
