Eric West and collaborator’s prepared one more Jupyter notebook-based tutorial, hosted here:
According to Eric’s email:
This one is on understanding and visualizing Cactus output files. So it's more about post-processing as opposed to Cactus itself. But the two are coupled. If you don't understand what Cactus is producing, and how to control it, you can't do the post-processing or visualization tasks that you want to do. So I try to explain a little about what Cactus is doing, the options you have, the structure of output files, and so on.
Two disclaimers: the tutorial does not address how to deal with Carpet output files, and it does not address how to handle output from multiple processors.
