[CIG-SHORT] pylith install error

Hi Charles
Yes, I have prescribed those three types of stresses, and I would like to get a zero displacement solution by balancing them out.
The top depth of the model is 500 m. 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.
Does this make sense?
Thanks for looking into it
Birendra

Hi Birendra,
I’m having difficulty
figuring out what you are trying to represent here. It
appears that you are using:
1. Gravitational stresses.
2. Initial stresses (presumably equal to the
gravitational stresses).
3. Normal
tractions on the top and right boundaries.
Is this correct?
Actually, looking a bit more,
these stresses don’t seem to balance. You have nonzero
normal stresses on your top boundary (they should be zero),
as well as at the top of your right side. Also, you have
nonzero initial stresses at the top of your mesh, which
won’t balance with gravitational stresses. It appears
you have an inconsistent stress state.
Cheers,
Charles

non-convergence of the nonlinear solver? I attached the
simulations files in my earlier email. Why is pylith not
able to converge to zero displacement solution at t=0 when
initial stresses, boundary tractions, and the body forces
are supposed to balance out? I am using pylith-1.9.0
installed from the binary.
