Detailed Description

Implementation of PETSc DM, managing interactions between mesh data structures and vectors and matrices.

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.

DM is abstract interface, here is it particular implementation for MoFEM code.
