DMDA#
“da” - A DM
object that is used to manage data for a structured grid in 1, 2, or 3 dimensions. In the global representation of the vector each process stores a non-overlapping rectangular (or slab in 3d) portion of the grid points. In the local representation these rectangular regions (slabs) are extended in all directions by a stencil width set with DMDASetStencilWidth()
. The vectors can be thought of as either cell centered or vertex centered on the mesh. But some variables cannot be cell centered and others
vertex centered; see the documentation for DMSTAG
, a similar DM
implementation which supports more general staggered grids.
