Jane,
The whole point of not imposing zero for all components in a Dirichlet
sense is that I am testing for a case where I have inhomogeneous normal
component of the normal stress, with the tangential stress being zero on
some boundaries.
This case is easy: the stress is only imposed weakly anyway, so you need
to put this into the bilinear form.
On some boundaries, I have zero normal flux and zero
tangential stress but I'm pretty sure this doesn't amount to the actual
components being zero anyway.
Correct. In this case, all you need to do is impose a nonzero normal
flux (for which I believe there is a function); the tangential stress
would have to be imposed in the bilinear form, but since it's zero there
is nothing to do (the term one would have to add to the bilinear form
just happens to be zero).
Best
W.
