Hi Dr. Wheeler, After making those changes, the codes works. However, the graph generated is weird and different from that generated with fipy trunk.
Hence I decide to use trunk. Is there any manual in PDF I can refer to? I tried to build the manual by python setup.py build_docs --pdf and also using --html. But I am getting errors from sphinx, so I was wondering if there is a manual you could provide me.
