# 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
