Function Documentation

◆ gpu_calculateMoments_R()

void gpu_calculateMoments_R	(	dccrg::Dccrg< SpatialCell, dccrg::Cartesian_Geometry > &	mpiGrid,
		const std::vector< CellID > &	cells_in,
		const bool	computeSecond,
		const bool	initialCompute )

Note: there is no single-cell GPU-only version of moments calculations, (calculateCellMoments) as that task is achieved through the ARCH-interface with no performance loss. Calculate zeroth, first, and (possibly) second bulk velocity moments for the given spatial cell. The calculated moments include contributions from all existing particle populations. The calculated moments are stored to SpatialCell::parameters in _R variables.

Parameters

mpiGrid	Parallel grid library.
cells	Vector containing the spatial cells to be calculated.
computeSecond	If true, second velocity moments are calculated.
initialCompute	If true, force re-calculation of outflow L1 sysboundary cell moments. (otherwise skipped as their VDF contents are not kept up to date)
