g -the global vector
Note
The vector values are NOT initialized and may have garbage in them, so you may need
to zero them.
The output parameter, g, is a regular PETSc vector that should be returned with
DMRestoreGlobalVector() DO NOT call VecDestroy() on it.
VecStride*() operations can be useful when using DM with dof > 1
Keywords
