DMMoabGetVertexDofsBlocked#

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

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

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.
