[CIG-SHORT] Question regarding spatial database with depth and lateral dependent properties

[Brad Aagaard]

Josimar,

See examples/2d/gravity, especially step03. For linear elasticity, the 
setup is relatively straightforward. With viscoelastic materials it can 
get tricky if the lateral density variation extends into the 
viscoelastic material, because the lighter material wants to move on top 
of the denser material.

Regards,
Brad
