Oh simply cubic. Say that you divide the main cell into 8 cubic parts and
then you get the average of stress in each of them (I simply want to compare
them). That should be easy in python (and as you say I can use utils
functions to get the stresses). My worry now is about the fact that the
interaction could in fact cross one of the domains. Is that a problem?
