[CIG-SHORT] 2D Simulations

[Brad Aagaard]

James-

PyLith does not support 2-D out-of-plane deformation. We have not 
implemented this capability because it involves writing extra code to 
handle this special case. The workaround is to construct a 3-D model and 
apply Dirichlet boundary conditions to enforce the desired symmetry and 
extract the solution along the centerline. This is more computational 
intensive but works reasonably well.
