I am trying to fill a vector based on global coordinate. As I am trying to use VecGetValues() on the global coordinate, I find it that argument goes out of range, since I am using global numbering rather than local numbering.

I find it really hard to work with the local numbering, how can I manage to create a kind of numbering on global level so that I could easily access to the nodes based on the new numbering. Thanks for your time. DMGetCoordinates() gives you a global vector. DMGetCoordinatesLocal() gives you a local vector. What are you trying to do?
