[CIG-SEISMO] using SPECFEM3D fot simulating gravity perturbation / PS

[Dimitri Komatitsch]

Dear Yixin Yao,

Please also make sure you get a recent version of the code, for instance 
by typing this:

git clone --recursive --branch devel 
https://github.com/geodynamics/specfem3d.git

because the current version of the users manual says this:

"OTHER ANNOUNCEMENT: SPECFEM3D can now perform gravity field 
calculations in addition (or instead of) seismic wave propagation only. 
See flag GRAVITY_INTEGRALS in file setup/constants.h.in.
Please also refer to 
http://komatitsch.free.fr/preprints/GJI_Martin_gravimetry_2017.pdf.
And yes, that is the reason why I added a falling apple on the cover of 
the manual :-)"

Best regards,
Dimitri.
