DMMoabGetVertexDofsBlocked

 Gets the global degree-of-freedom for the first field (component) defined on an array of locally owned MOAB mesh vertices. It's utility is when performing Finite-Difference type calculations where vertex traversal is faster than element-wise assembly that is typically done in FEM calculations.

Synopsis

#include "petscdmmoab.h"   
PetscErrorCode DMMoabGetVertexDofsBlocked(DM dm, PetscInt** dof)
Not Collective

Input Parameters

dm -the discretization manager object

Output Parameter

dof -the blocked global degree-of-freedom index array in the discrete representation (Vec, Mat) that is vertex-based based on local numbering
