[CIG-SEISMO] Question about SPECFEM 3D GLOBE

[Dimitri Komatitsch]

Dear Juwan Kim,

This means that the code became unstable in the fluid (i.e., in the 
outer core of the Earth). Please email us your DATA/Par_file and we will 
try.

Other developers at Princeton have also recently noticed some 
instabilities in the fluid region therefore we need to doublecheck.

That part of the code used to be very stable, but because we have many 
developers worldwide we cannot exclude that changes made elsewhere in 
the code had side effects for the fluid region.

Thank you,
Best regards,

Dimitri Komatitsch.

Dear whom it may concerns,

I am Juwan Kim pursuing a Masters degree in Geophysics at the Lab of 
Geophysics in the Chonbuk National University in South Korea.
We have downloaded your Specfem 3D Globe pakage and are trying to make 
synthetic seismograms through 3-D earth model.

For test to our MPI system, we've run the program with 1-D model. After 
I run the solver, there is an error message like below.

forward simulation became unstable and blew up in the fluid
  Error detected, aborting MPI... proc            0

What should I do in order to solve this problem? Could you give me an 
advice or suggestion?
For more understanding, I attach the file of error and result.

Best regard
Juwan Kim
