isDuneGridFormat() [1/2]

bool Dune::DuneGridFormatParser::isDuneGridFormat ( const std::string & filename )

static

check whether a file is in dune grid format

This is just a convenience method. It calls isDuneGridFormat with a std::ifstream.

Parameters

filename

file to check

Returns

whether the keyword 'DGF' was found

isDuneGridFormat() [2/2]

bool Dune::DuneGridFormatParser::isDuneGridFormat ( std::istream & input )

static

check whether a stream is in DUNE grid format

Actually checks whether the stream starts with the keyword 'DGF'.

Parameters

input

std::istream to check

Note

The stream must support seeking.

Returns

whether the keyword 'DGF' was found

readDuneGrid()

bool Dune::DuneGridFormatParser::readDuneGrid	(	std::istream &	input,
		int	dimG,
		int	dimW )

parse dune grid format from stream

This method actually fills the vtx, element, and bound vectors.

Parameters

	input	std::istream to read the grid from
[in]	dimG	dimension of the grid (i.e., Grid::dimension)
[in]	dimW	dimension of the world (i.e., Grid::dimensionworld)

Note

The stream must support seeking.

Returns

whether reading succeeded
