Subject: Re: STRUCT Limit in pressure for convergence

The boundary conditions should mimic whatever it is you are modeling. You
shouldn't add more constraints just because it converges with them. Even if
you get a converged solution, it doesn't do you any good if it doesn't
represent the behavior of the lithosphere.

>From what you have described, the model looks like it is working correctly;
you're just getting gross material yielding. If it's not replicating real
world behavior, then some of your assumptions are wrong. It could be
boundary conditions, or it could be material properties, or perhaps the
material behavior model that you've chosen isn't applicable, or something
else.

I don't really know enough about the behavior of the lithosphere to give
sound advice on how to properly model it.
