# DMMoabGetVertexDofsBlockedLocal

Gets the local degree-of-freedom for the first field (component) defined on an array of locally owned MOAB mesh vertices.

## Synopsis

    #include "petscdmmoab.h"
    PetscErrorCode DMMoabGetVertexDofsBlockedLocal(DM dm, PetscInt **dof)

Not Collective

## Input Parameters

- dm - the discretization manager object

## Output Parameter

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

## Note

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.
