There shoud be no problem with this. If you can define the indicial
expressions for the stress tensor then the expressions for its components in
different coordinate systems can be found by means ic_convert(). Please look
demo files in share/tensor

This is hardly possible currently. Though, I would't say that it is impossible
at all. You can try to play with contrib/gentran.
