[CIG-SHORT] Problem with modeling viscoelastic magma chamber

[Francisco Delgado]

Hello, I've been adapting the magma chamber example to include a
viscoelastic medium surrounding the pressurized cavity and when I run the
code I get the following error:


 >>
/Applications/pylith-2.0.0-darwin-10.6.8/lib/python2.7/site-packages/pylith/problems/TimeDependent.py:137:run

 -- timedependent(info)

 -- Preparing for prestep with elastic behavior.

Fatal error. Calling MPI_Abort() to abort PyLith application.

Traceback (most recent call last):

What does this error mean and how can I fix it??


Thanks
