[CIG-SEISMO] A question on SPECFEM3D

[Dimitri Komatitsch]

Hi,

The internal mesher uses linear interpolation between the bottom and top 
surfaces, thus each of them can be titled and even have significant 
topography, but they cannot cross (otherwise the Jacobian becomes 
negative). In such a case you need to switch to CUBIT, Gmsh, GiD or similar.

Best wishes,
Dimitri.
