## DA Examples

DA objects are used to manage parallel communications for structured mesh problems in PDE-based (or other) simulations.

ex1.c: Tests VecView() contour plotting for 2d DAs
ex2.c: Tests DAGlobalToNaturalAllCreate() using contour plotting for 2d DAs
ex3.c: Tests DAGetInterpolation for nonuniform DA coordinates
ex4.c: Demonstrates various vector routines
ex5.c: Tests DAGetElements() and VecView() contour plotting for 2d DAs
ex6.c: Demonstrates using 3 DA's to manage a slightly non-trivial grid
