[CIG-SEISMO] Using xmeshfem3D in SPECFEM3D

[Chris Morency]

Hi Shahar,

You are right concerning the second NMATERIALS in the manual, it should read NREGIONS, and you also need the NZs To be defined.

As for a mesh for this area on SPECFEM3D am afraid you would have to built it, and indeed CUBIT would be the tool of choice. But others may be able to weigh in on that.

Have you tried using a couple of chunks with SPECFEM3D_GLOBE  instead ?
