Detailed Description

a distributed structured dataset that is implicitly connected among partitions without abutting.

This creates a gap between partitions and introduces a cell that spans multiple zones. This typically arises with finite difference grids, which are partitioned with respect to the nodes of the grid, or, when a filter samples the grid, e.g., to get a lower resolution representation.

This class is intended as a lower-level helper for higher level VTK filters that provides functionality for resolving the implicit connectivity (gap) between two or more partitions of a distributed structured dataset.

Warning

The present implementation requires:

one block/grid per rank.
2-D (XY,YZ or XZ planes) or 3-D datasets.
node-center fields must match across processes.
