Hi David,
with simple.py, the results are stored in output files to be post-processed elsewhere (e.g. with mayavi). But you can do some post-processing also during the computation by using the post_process_hook function, see [1] and other examples. For full control, writing a proper script such as the "interactive" examples is needed (simple.py just builds a Problem instance for you...).
Otherwise, there is no "dangerous zone" documentation, so try checking the examples and do not hesitate to ask more.

okay making progress understanding simple.py now. If there's "some lower-level documentation for people who know enough to be dangerous" that's great. If not, I'll get there eventually.
