Hi Carlos, Max did write a script to do a volume calculation, you can find it on his script repository page here: http://moi.maxsm.net/media/files/ look for the one named CVolume.

A full fledged stress analysis is likely to be an extremely much larger amount of work though, it's not likely to be feasible to implement in script. There are entire complex programs devoted to doing that, look for Finite Element Analysis (FEM) programs which you can import your MoI model into.
