Here is the caller graph for this function:

◆ calcCellParameters()

void projects::Diffusion::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
cellPointer to the spatial cell to be handled.
tThe 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 139 of file Diffusion.cpp.

◆ fillPhaseSpace()

Realf projects::Diffusion::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
popIDParticle 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.

◆ getParameters()

void projects::Diffusion::getParameters ( void )
overridevirtual

Get the value that was read in.

Reimplemented from projects::Project.

Definition at line 61 of file Diffusion.cpp.

Here is the call graph for this function:

◆ initialize()

bool projects::Diffusion::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.
