[CIG-SHORT] principle stress

[Brad Aagaard]

Xiao,

As Charles mentioned in his email yesterday, PyLith does not provide a 
means to output principal stresses. PyLith outputs the stress tensor 
components, so you can compute the principal stresses and their 
orientation using your favorite post-processing software, like Matlab or 
just plain Python via numpy (see the numpy.linalg.eigh function). The 
PyLith binary includes Python and the numpy module.

Regards,
Brad
