	Compute 0th, 1st and 2nd velocity moments (RHO,VX,VY,VZ,P_11,P_22,P_33 and *_DT2) for all cells in the grid directly from distribution function. The simulation should be at a true time-step! This is at the moment only called at initialisation.

Function Documentation

calculateAcceleration()

void calculateAcceleration	(	dccrg::Dccrg< SpatialCell, dccrg::Cartesian_Geometry > &	mpiGrid,
		const Real	dt )

Accelerate all particle populations to new time t+dt. This function is AMR safe.

Parameters

mpiGrid	Parallel grid library.
dt	Time step.

calculateCellMoments()

void calculateCellMoments	(	spatial_cell::SpatialCell *	cell,
		const bool &	computeSecond,
		const bool &	computePopulationMomentsOnly,
		const bool &	doNotSkip )

Calculate velocity moments for the given spatial cell. This function is defined in the arch_moments.cpp file.

Calculate zeroth, first, and (possibly) second bulk velocity moments for the given spatial cell. The calculated moments include contributions from all existing particle populations.

Parameters

cell	Spatial cell.
computeSecond	If true, second velocity moments are calculated.
doNotSkip	If false, DO_NOT_COMPUTE cells are skipped.
