walberla::mesa_pd::data::HashGrids::HashGrid::Cell Struct Reference

Detailed Description

Data structure for representing a cell in the hash grid (used by the 'Hierarchical Hash Grids' coarse collision detection algorithm).

Public Attributes
ParticleIdxVector *	particles_
	The cell's particle container that stores (handles to) all the particles that are assigned to this cell.
offset_t *	neighborOffset_
	Pointer to an array that is storing offsets that can be used to directly access all the neighboring cells in the hash grid.
size_t	occupiedCellsId_
	The cell's index in the occupiedCells_ vector.

Member Data Documentation

neighborOffset_

offset_t* walberla::mesa_pd::data::HashGrids::HashGrid::Cell::neighborOffset_

Pointer to an array that is storing offsets that can be used to directly access all the neighboring cells in the hash grid.

occupiedCellsId_

size_t walberla::mesa_pd::data::HashGrids::HashGrid::Cell::occupiedCellsId_

The cell's index in the occupiedCells_ vector.

particles_

ParticleIdxVector* walberla::mesa_pd::data::HashGrids::HashGrid::Cell::particles_

The cell's particle container that stores (handles to) all the particles that are assigned to this cell.

Note that only a pointer to such a particle container is stored: in order to save memory, this container object is only allocated as long as there are particles assigned to this cell.
