[CIG-SEISMO] Can SPECEM3D do gravit inversion?

[Dimitri Komatitsch]

Hi Ming,

Thanks for your message! This is indeed an interesting topic. My friend 
Roland Martin has a nice paper that has just appeared on this: 
http://komatitsch.free.fr/preprints/GJI_Martin_gravimetry_2017.pdf

thus let me cc Roland to see what the current version of SPECFEM3D can 
do (it can do 3D modeling for sure, but I think the gravity inversion 
part was performed outside of SPECFEM using scripts for now (?); Roland 
can tell us more about this, he is the expert on that).

Thanks!
Cheers,
Dimitri.
