[CIG-SEISMO] New mesh construction for SPECFEM3D?

[Jeroen Tromp]

Dear Steve:

We (Dimitri Komatitsch's group at Pau and my group at Princeton) are 
currently working on a new version of SPECFEM3D, SPECFEM3D_SESAME, which 
has all the attributes of SPECFEM3D and accommodates any unstructured 
mesh. These meshes may be constructed in Cubit (cubit.sandia.gov) and 
Gocad (www.gocad.org), are partitioned and load-balanced based upon 
ParMetis (glaros.dtc.umn.edu/gkhome/metis/parmetis/overview), before use 
by a brand new SEM solver. The basic forward solver is ready, but we are 
currently adding additional features such as attenuation, acoustic and 
poroelastic solvers, adjoint capabilities, etc. We are aiming for 
release of the new software in the summer.

Sincerely,

Jeroen Tromp
