[CIG-SHORT] some confusion about modeling

[fuqiang shi]

Dear,Sir,

  I am a new learner of cubit+pylith. I am sorry to disturb you for some
unexpected running errors, and I have tried all my best to solve them, but
no answer.
The error is totally like this:
Maybe it have some relation with the solver, but I haven't do any modify on
the solution parameter of the provided example.  I only modify the model
slightly and my model is also attached (s. attachment).
Your consideration and suggestions upon my request will be highly
appreciated. I am looking forward to your favorable reply at your earliest
convenience.

                                                                  Sincerely,


                                                               Fuqiang Shi
