[CIG-SHORT] Output error with cohesion on faults

[Brad Aagaard]

Joseph,

This sounds like a convergence or tolerance issue. If this is a 
quasi-static simulation, have you verified that the nonlinear and linear 
solves are converging at every time step? For an example of how to do 
this, see Session IV (step03) in the 2015 PyLith Tutorial at
https://wiki.geodynamics.org/software:pylith:cdm2015.

If you send another message to the list, please include the version of 
PyLith you are using and a description of the problem you are running 
(diagrams are usually very helpful).

Regards,
Brad
