[CIG-SHORT] CSEC benchmarks pylith files on Github?

[Ekaterina Bolotskaya]

Dear Brad,

I'm using Pylith 2.1.3 and my info outputs are .vtk 
Please find the two info files (fault and statevars) and the log attached.
Hope, that helps.

Thanks!

Best regards,

The files are in dynamic/scecdynrup/tpv102. These files may need
updating for work with PyLith v2.X.X.

I think the examples you list are the ones we have for quasistatic modeling.

Do you have sufficient Dirichlet BC to eliminate all rigid body motion
(translation and rotation)? If so, turn on the KSP and SNES monitors and
send your JSON parameter file (generated automatically in v2.2.1)  and
your entire log.

Brad
