[CIG-SHORT] Modifying volcano_chamberdike example

[Nuria Lumbreras]

Dear Sirs,

My name is Nuria Lumbreras and I am working with PyLith for my master's
thesis.

With volcano_chamberdike example for Ruapehu volcano as a starting point,
I've changed the topography and geometry trying to model the Tagoro volcano
(which erupted in 2011 for first time) in El Hierro (Canary Islands). I am
using a spherical magma chamber as well, and a 12km-length horizontal dike
instead of a vertical one.

However, I am finding some troubles when trying to set a time dependence
for this last one. What I want to get is a temporally advancing dike, which
is, no dike at time zero, and the whole dike (12km) after three months,
evolving in a constant rate (6km at time 1.5 months). Would you please send
me more information about this?

I also would appreciate if you could explain to me how to run the model
with an spheroid. When I scale the sphere (in the z axis in my case), I can
visualize the spheroid in CUBIT, but when I run the Pylith script I get the
following message error:

RuntimeError: Could not find group of points 'magma_chamber' in PETSc DM
mesh.
application called MPI_Abort(MPI_COMM_WORLD, -1) - process 0
/home/nuria/pylith/bin/nemesis: mpirun: exit 255
/home/nuria/pylith/bin/pylith: /home/nuria/pylith/bin/nemesis: exit 1

Thank you for your assistance.

Best regards,

Nuria Lumbreras
