         Does DMPlexCreateFromCellList remove duplicate nodes in mesh ? I
am creating mesh using gmsh Extrude options, I see that the resulting mesh
has duplicate nodes. Currently i preprocess the mesh data to remove the
duplicate nodes before passing it to DMPlex CreateFromCellList.

Is there a change in node ordering of the cell ?

One a different note,  any plans to provide functionality similar to
DMPlexComputeCellGeometry for FVM based assembly. I am looking for things
like the following to do cell wise assembly
1. Contribution to Voronoi volume associated with each point
2. Contribution to Surface area
3. Edge length
