fillCellAcBuffer()

GMC_API_EXPORT void GmFileIOUtils::fillCellAcBuffer	(	GmTaskManager *	tm,
		const GmCellMesh *	mesh,
		const GmCellAccessor *	cac,
		const GmValueAccessor *	coordAc,
		int	dimFilter,
		const QVector< int > &	indexer,
		int	cellStart,
		int	cellCount,
		GmWBuffer &	bbuf )

Utillity to fill a buffer with cell accessor data. Gema tasks are used to speed up accessors with lua user functions.

Parameters

mesh	The mesh that contains the Cell data to be saved
cac	The accessor providing Cell data.
dimFilter	A filter that can specify that only a single dimension of a vector (or matrix) data should be exported. Use -1 to specify that all dimensions should be saved.
Indexer	A vector with cellId and its global index start position
cellStart	Where in the Indexer we are starting from
cellCount	How many cells we are processing in this batch
bbuf	The buffer to write to

fillGaussAcBuffer()

GMC_API_EXPORT int GmFileIOUtils::fillGaussAcBuffer	(	GmTaskManager *	tm,
		const GmElementMesh *	mesh,
		const GmGaussAccessor *	gac,
		int	rule,
		int	dimFilter,
		const QVector< GmFileFilter::Indexer > &	preIndex,
		int	cellStart,
		int	cellCount,
		int	valueStart,
		GmWBuffer &	bbuf )

Utillity to fill a buffer with gauss accessor data. Gema tasks are used to speed up accessors with lua user functions.

Parameters

mesh	The mesh that contains the Gauss data to be saved
gac	The accessor providing Gauss data.
rule	The integration rule number
dimFilter	A filter that can specify that only a single dimension of a vector (or matrix) data should be exported. Use -1 to specify that all dimensions should be saved.
preIndex	A vector with cellId and its global index start position
cellStart	Starting cell index
cellCount	How many cells we are processing in this batch
valueStart	Starting global index for values in this batch
bbuf	The buffer to write to

Returns

Returns number of entries processed (sum of processed cell's integration points)

fillNodeAcBuffer()

GMC_API_EXPORT void GmFileIOUtils::fillNodeAcBuffer	(	GmTaskManager *	tm,
		const GmMesh *	mesh,
		GmValueAccessor *	nac,
		int	dimFilter,
		const TransformF &	transformFunc,
		const QVector< int > &	indexer,
		int	nodeStart,
		int	nodeCount,
		GmWBuffer &	bbuf )

Utillity to fill a buffer with node accessor data. Gema tasks are used to speed up accessors with lua user functions.

Parameters

mesh	The mesh that contains the Cell data to be saved
nac	The accessor providing Node data.
dimFilter	A filter that can specify that only a single dimension of a vector (or matrix) data should be exported. Use -1 to specify that all dimensions should be saved.
Indexer	A vector with nodeId and its global index start position
nodeStart	Where in the Indexer we are starting from
nodeCount	How many nodes we are processing in this batch
bbuf	The buffer to write to
