Hi,

I am playing with Peri3dController with label e.g. 'biax', but I find the stress returned by biax.stress is different from that by calling utils.stressTensorOfPeriodicCell(). The formula used by stressTensorOfPeriodicCell is what we commonly adopt in DEM. How stress is calculated in Peri3dController?
