[CIG-SEISMO] some problems in gravity calculation of SPECFEM3D

[zm]

Hi everyone,

I tried to use specfem3d to calculate gravity integration of a very 
simple model(see attachment 2,the central block has different 
density).However,it seems the gravity field is quite rough and 
uneven,look at attachment 1,it seems related to the mesh,but it is a 
simple and regular mesh,what could it be?Anyone has any ideas,thanks!

Best
