struct exahype2::CellFaceData< inType, outType >

Represents the faces of one cell, with a total of 2*Dim faces per cell For ADER QIn will contain the values, QOut would contain the fluxes The faces can still each be made to contain either only the values for the given cell, or those and the neighbours' values.

◆ CellFaceData() [1/3]

template<typename inType , typename outType >

exahype2::CellFaceData< inType, outType >::CellFaceData	(	inType *	QIn_[2 *DIMENSIONS],
		const tarch::la::Vector< DIMENSIONS, double > &	cellCentre_,

		int	targetDevice_ = `tarch::accelerator::Device::DefaultDevice`
	)

Construct patch data object for one single cell.

Usually, I do so only to be able to use the same kernels everywhere: Kernels accept CellFaceData, i.e. multiple patches. Even if we have only one cell, we thus wrap this cell's data into an instance of CellFaceData and pass it in. The id can be set to any dummy in this case, as we know which task has wrapped this single cell, i.e. we usually do not read it later.

int* exahype2::CellFaceData< inType, outType >::id

Id of underlying task.

Required when we fuse many enclave tasks and load them off to the GPU, as we have to know afterwards which outcome corresponds to which task.
