[CIG-SEISMO] Asking SPECFEM2D SU format

[Dimitri Komatitsch]

Dear Jungrak,

Yes, CUBIT can be used in 2D as well. We often use Gmsh in the 2D case ( 
http://geuz.org/gmsh ), but CUBIT is valid as well. To input 2D CUBIT 
meshes into SPECFEM2D you can use some of the scripts that we have in 
directory "UTILS/cubit2specfem2d".

Regarding the canyon example, it is an old mesh that I created a long 
time ago using a small Fortran mesher that I wrote myself back then... 
this is why it looks different (and nowadays it would be better to use 
CUBIT or Gmsh).

The example in "EXAMPLES/salt_dome_CUBIT_mesh" is a bit unusual: we have 
lost the original CUBIT journal files, thus the only thing we have is 
the original geometry and the final meshes, but not the CUBIT commands 
to create them. If you need them, the easiest thing to do would be to 
import the geometry in CUBIT and mesh it again from scratch, since that 
mesh is simple. (if you do that, please email us the journal file, we 
would be interested in adding it to that directory).

Thank you,
Best regards,

Dimitri.
