[CIG-SHORT] PyLith: Stresses not transmitted throughout the domain from Drichlet BCs on CUBIT Mesh

Hello Developers,

I have created the attached geometry (5kmx5kmx4.1km) in CUBIT. It has three
layer of materials (2000m+100m+200m) and a vertical fault (along Z axis)
1000m to the left from the positive X-plane boundary. The exported Exodus
mesh is then used to run a PyLith simulation with Dirichlet displacement
and displacement rate BCs (e.g. PyLith Tutorial 'step12.cfg') on +x and -x
sides. The simulation runs fine but even after running for 100 years I
don't see any stress being transmitted to the interior domain. All I can
see is the stress changes in the boundary elements where the Dirichlet BCs
are applied. I am not sure if it is caused by improper meshing or boundary
conditions.

Attached also are the .cfg files, geometry journal file, and stress output
file from simulation. I would highly appreciate any help.
