Domain

The simulation domain is devided into macroscopic cells in lexicographic ordering. These macroscopic cells are extended by a ghost layer in each direction, effectively making the domain have a size of GlobalNumberMacroscopicCells_d + 2.

Every point within the simulation domain can be referenced by globalCellIndex, localCellIndex.

• globalCellIndex can be expressed in terms of a vector index or a linearised index over the whole domain

• local refers to an index being specific to a rank
