[CIG-SHORT] Smoothing Issues

[Brad Aagaard]

Nick,

For starters please see the recent discussion with the subject "Question 
about accuracy in PyLith" at
http://lists.geodynamics.org/pipermail/cig-short/2016-October/thread.html

In addition to evaluating mesh quality, to get rid of checker-boarding 
you should also consider using a finer mesh and/or tighter solver 
tolerances.

Regards,
Brad
