I would like to ask about the orientation of the stress and strain tensor in PyLith result.
As previously, I have mentioned that I run the simulation of 2D subduction and put also a splay fault in the geometry. I would like to calculate the coulomb stress on this splay fault.
My question is, do the stress and strain tensor in Pylith already have orientation thus I can calculate the coulomb stress directly using the stress and strain tensor from the result? Or I should consider the geometry (strike,dip) of the splay fault manually and do post-calculation to retrieve the strain and normal traction?
Thank you in advance.
