[CIG-SHORT] pylith install error

Hi Charles

So if I set the initialstress = 0 at z = -500 m and initialstress =  rho*g*2000 at z = -2500 m, and modify the topboundary and rightboundary spatialdb accordingly (files attached), I should get zero displacement solution? I don't get that. 

Thanks and regards
Birendra

 Hi Birendra,
 
 The gravitational stresses are
 independent of any vertical coordinate shift, which means
 stresses at the surface should still be zero.  If you want
 to represent stresses at depth, you will need to include the
 overlying material.
 
 Cheers,
 Charles

 Therefore, I have a non-zero traction at the top boundary to
 balance the initial stress, which is also non-zero at the
 top i.e. at the 500 m depth. On the right, I am trying to
 represent a horizontal compression which is 0.7 times the
 vertical stress (overburden), i.e. a normal faulting
 regime.
