Detailed Description

template<class GridView>
class Dune::GmshWriter< GridView >

Write Gmsh mesh file.

Write a grid using the given GridView as an ASCII Gmsh file of version 2.0.

If the grid contains an element type not supported by gmsh an IOError exception is thrown.

All grids in a gmsh file live in three-dimensional Euclidean space. If the world dimension of the grid type that you are writing is less than three, the remaining coordinates are set to zero.

Constructor & Destructor Documentation

GmshWriter()

template<class GridView >

Dune::GmshWriter< GridView >::GmshWriter ( const GridView &  gridView, int  numDigits = 6  )

inline

Constructor expecting GridView of Grid to be written.

Parameters

gridView	GridView that will be written.
numDigits	Number of digits to use.

Member Function Documentation

setPrecision()

template<class GridView >

void Dune::GmshWriter< GridView >::setPrecision ( int  numDigits )

inline

Set the number of digits to be used when writing the vertices. By default is 6.

numDigits Number of digits to use.

write()

template<class GridView >

void Dune::GmshWriter< GridView >::write ( const std::string &  fileName, const std::vector< int > &  physicalEntities = std::vector<int>(), const std::vector< int > &  physicalBoundaries = std::vector<int>()  ) const

inline

Write given grid in Gmsh 2.0 compatible ASCII file.

Parameters

fileName	Path of file. This method does not attach a ".msh"-extension by itself.
physicalEntities	Physical entities for each element (optional).
physicalBoundaries	Physical boundaries (optional).

Opens the file with given name and path, stores the element data of the grid and closes the file when done.

If the optional parameter physicalEntities is provided, each element is written with a tag representing its physical id.

If the optional parameter physicalBoundaries is provided, also the boundaries are written on file with the corresponding physical value.

The physicalBoundaries vector need to be sorted according to the intersection boundary segment index.

Throws an IOError if file could not be opened or an unsupported element type is encountered.
