DM Examples

DM objects are used to manage communication between the algebraic structures in PETSc (Vec and Mat) and mesh data structures in PDE-based (or other) simulations. See, for example, DMDACreate().

ex1.c: Define a simple field over the mesh\n\n
ex2.c: Read in a mesh and test whether it is valid\n\n
ex5.c: Load and save the mesh and fields to HDF5 and ExodusII\n\n
