a question about the nodal graph of parmetis

as we all known that metis provide mesh2nodal and mesh2dual function,and then metis can make a partition of the nodal graph.but parmetis only provide parallel partition of the dual graph, how can it to realize parallel nodal graph partition?

RE: You need to construct the

You need to construct the nodal graph yourself and then use parmetis to partition it.

RE: thank you for guide me
