Hi Avery,

Could you be a little more specific about what is failing in your model?
What is the input file you are using, and what does the output look like?
If you try it in 2D, do things appear to be working correctly? In general,
it would be useful for us to have a minimal example that reproduces your

There is a crustal deformation cookbook that is in 3D (contributed by
Cedric Thieulot and Anne Glerum) which you could run running to verify
things are working. At the moment, the material model on which it relies is
waiting to be merged, but you could try checking that out.
