DMStagGet1dCoordinateArraysDOFRead - extract 1D coordinate arrays

Logically Collective

A high-level helper function to quickly extract raw 1D local coordinate arrays.

Checks that the coordinate DM is a DMProduct or 1D DMStags, with the same number of dof.

Check on the number of dof and dimension ensures that the elementwise data

is the same for each, so the same indexing can be used on the arrays.

Input Parameter:

. dm - the DMStag object

Output Parameters:

. arrX,arrY,arrX - local 1D coordinate arrays
