Detailed Description

Class for storing the AMR hierarchy as a collection of tiles.

This class only makes sense in terms of a grid which uses constant-size grid, which is a restriction we happily accept when using particles. This class decomposes the AMR hierarchy into such tiles, each tile being the cells spanned by the blockingFactor^SpaceDim grid patch.

Constructor & Destructor Documentation

LevelTiles()

LevelTiles::LevelTiles ( const DisjointBoxLayout &  a_grids, const int  a_blockingFactor  )

noexcept

Full constructor - puts object in usable state.
