Newbie question - hmetis and node positions


I've got two questions which may have very simple answers. Apologies for my ignorance.

1. Is it possible to give node positions/dimensions as constraints for partitioning within hmetis? In other words, can the location of the nodes or the actual size of the nodes have any impact on which partition it will belong to?

2. Is there a specific order as to how a graph will be partitioned i.e. when having 4 partitions, is the 0th partition the top left, 1st right, 2nd bottom left, 3rd bottom right etc?

Thank you for your help.
