Hi all,it's my understanding that the way ufc ordering works is for adjacent
cells to
alternate orientation so that they traverse edges (and faces in 3d) the same
global
way.  It seems that in 2d this is equivalent to two-coloring a graph (each
cell is either
clockwise or counterclockwise)

Has there been any thought to issues at imposing ufc ordering in parallel,
where each
process has to assign an orientation to the first local cell, and different
processors
might disagree?
