Detailed Description

This class implements the HalfShell Method. Halo is only imported, if it lies within the half shell. The half shell is defined using the same traversal scheme as the VectorizedCellProcessor uses for determining, whether or whether not to calculate the macroscopic values, i.e: cellIndex1 < cellIndex2. As LinkedCells defines the cellIndex using z as the major array index (then y, then x), we will do the same here: if z<z_domain, we don't import the region. if z>z_domain we import it. if z within z_domain: y determines the procedure. The HalfShell method requires forces to be exchanged.

Member Function Documentation

getHaloExportForceImportRegions()

std::vector<HaloRegion> HalfShell::getHaloExportForceImportRegions ( HaloRegion &  initialRegion, double  cutoffRadius, bool  coversWholeDomain[3], double  cellLength[3]  )

inlineoverridevirtual

Returns the export halo Regions of the process. These regions are also the ForceImport Regions of a process, if it is a force-importer. This indicates, where the processes lie that require halo copies from the current process.

Parameters

initialRegion	boundary of the current process
cutoffRadius
coversWholeDomain
cellLength

Returns

vector of regions

Implements ZonalMethod.

getHaloImportForceExportRegions()

std::vector<HaloRegion> HalfShell::getHaloImportForceExportRegions ( HaloRegion &  initialRegion, double  cutoffRadius, bool  coversWholeDomain[3], double  cellLength[3]  )

inlineoverridevirtual

Returns the import halo Regions of the process. These regions are also the ForceExport Regions of a process, if it is a force-exporter. This indicates, where the processes lie that require halo copies from the current process.

Parameters

initialRegion	boundary of the current process
cutoffRadius
coversWholeDomain
cellLength

Returns

vector of regions

Implements ZonalMethod.
