Here is the caller graph for this function:

◆ calcCellParameters()

void projects::Fluctuations::calcCellParameters	(	spatial_cell::SpatialCell *	cell,
		creal &	t )

overridevirtual

Calculate potentially needed parameters for the given spatial cell at the given time.

Currently this function is only called during initialization.

The following array indices contain the coordinates of the "lower left corner" of the cell: CellParams::XCRD, CellParams::YCRD, and CellParams::ZCRD. The cell size is given in the following array indices: CellParams::DX, CellParams::DY, and CellParams::DZ.

Parameters

cell	Pointer to the spatial cell to be handled.
t	The current value of time. This is passed as a convenience. If you need more detailed information of the state of the simulation, you can read it from Parameters.

Print a warning message to stderr and abort, one should not use the base class functions.

Reimplemented from projects::Project.

Definition at line 181 of file Fluctuations.cpp.

Here is the call graph for this function:

◆ fillPhaseSpace()

Realf projects::Fluctuations::fillPhaseSpace	(	spatial_cell::SpatialCell *	cell,
		const uint	popID,
		const uint	nRequested ) const

overridevirtual

Calculates the distribution function contents for the spatial cell and population in question NOTE: This function is called inside parallel region so it must be declared as const. This function will contain a loop over nRequested velocity blocks, with the block GlobalIDs provided in the GIDlist buffer, storing phase-space densities in the bufferData buffer.

Parameters

popID Particle species ID.

Returns: The total stored number density of the cell for this population The physical unit of this quantity is 1/m^3.

Implements projects::Project.

Here is the call graph for this function:

◆ getParameters()

void projects::Fluctuations::getParameters ( void )

overridevirtual

Get the value that was read in.

Reimplemented from projects::Project.

Definition at line 70 of file Fluctuations.cpp.

Here is the call graph for this function:

◆ getV0()

std::vector< std::array< Real, 3 > > projects::Fluctuations::getV0	(	creal	x,
		creal	y,
		creal	z,
		const uint	popID ) const

overridevirtual

Return a vector containing the velocity coordinate of the centre of each ion population in the distribution.

This function is used by findBlocksToInitialize() to start the search of the extent of the distribution along each axis. The extension to a vector allows to have more than one population in each spatial cell.

See also: findBlocksToInitialize

Implements projects::TriAxisSearch.

Definition at line 232 of file Fluctuations.cpp.

◆ initialize()

bool projects::Fluctuations::initialize ( void )

overridevirtual

Initialize project. Can be used, e.g., to read in parameters from the input file.

Initialize the Project. Velocity mesh and particle population parameters are read from the configuration file, and corresponding internal variables are created here. NOTE: Each project must call this function!

Returns: If true, particle species and velocity meshes were created successfully.

void projects::Fluctuations::setProjectBField	(	fsgrids::perbspan	perb,
		fsgrids::bgbspan	bgb,
		fsgrids::technicalspan	technical,
		FieldSolverGrid &	fsgrid )

overridevirtual

Set the background and perturbed magnetic fields for this project.

Parameters

perBGrid	Grid on which values of the perturbed field can be set if needed.
BgBGrid	Grid on which values for the background field can be set if needed, e.g. using the background field functions.
technical	Technical fsgrid, available if some of its data is necessary.
