[aspect-devel] free surface with non-zero surface pressure

Hi all,

I'm wondering whether is any reason why the free surface option could not
be run with a traction boundary condition at the free surface.  Here, I
have in mind applying a normal force at the surface, which could be due to
an ice sheet, sediment load, etc., and then the surface would be allowed to
deform under that load.

This could be framed as two questions:
1. Can surface pressure be combined with a free surface in principle in
2. Are there any barriers to implementing these together in either the 1.4
release or the development version?

Looking forward to hearing your thoughts.
