◆ getNeighboringProcessOffsets()

std::map< uint_t, std::vector< Vector3< real_t > > > walberla::blockforest::BlockForest::getNeighboringProcessOffsets ( ) const

overridevirtual

For every neighboring process one or more offsets must be returned.

Normally, for every neighboring process exactly one offset is returned: (0,0,0). Only in case of periodicity this offset can be different from (0,0,0)! If the offset is different from (0,0,0), the x-component must be identical to either 0 or +/- the x-width of the domain. The same applies for y and z. What this offset is supposed to do: Each block in 3D has 26 neighborhood regions. Suppose we leave block A in direction (-1,0,0) and enter the neighboring block B, which is stored on another process. If A is located at the x-min border of the domain and the simulation is only periodic in x-direction, block B must be located at the x-max border of the domain and the corresponding offset to block B - or more precisely to the process storing block B - is (+ x-width of the domain, 0, 0). Since each process can store multiple blocks and a simulation can be periodic in more than just one direction, there may be multiple offsets to another process - hence the std::vector. For an actual implementation of "getNeighboringProcessOffsets()" see BlockForest.cpp.
