[CIG-SEISMO] suspicious bug of the gravity calculations

[赵明]

Hi Everyone,
I tried the gravity field calculation of SPECFEM3D using the given example: homogeneous_halfspace_HEX8_elastic_absorbing_Stacey_5sides.However,I found the results seem to be abnormal at some observations.
Since it is a homogenous model,the gravity value should be the same to the observation on the surface.However,look at the toto.ps,there are some place (very likely to be the boundary of some elements) the gravity is abnormal. 
Best regardsMing Zhao
