Data Management (DM)#

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 structured grids DMDA, for staggered grids DMSTAG, and for unstructured grids DMPLEX. Users guide chapter: DM: Interfacing Between Solvers and Models/Discretizations.
