Billy,
We often have problems displaying images on Windows with mayavi and
matplotlib. Unfortunately, these are completely independent of FiPy
and so we are at the mercy of those packages.
You're obviously using the matplotlib viewer and not the mayavi
viewer. FiPy selects one or the other. You can specify this by setting
the "FIPY_VIEWER" environment variable to "matplotlib" or "mayavi".
One thing that you might want to try is placing a couple of
"viewer.plot()" statements followed by a "raw_input("press
something")" statement before the loop starts on line 296 of
simpleTrenchSystem.py. That allows you to reposition the windows so
that you can actually see them and not have other windows covering
them.
If either alternating between matplotlib and mayavi or the extera
viewer.plot() statements doesn't seem to cut it, then I'll try running
on the windows machine we have here or a virtual one and see if there
isn't a more pervasive issue. Anyway, try the above and get back to
me.
Also, you don't necessarily have to view the results as the simulation
is running. You can always switch of the viewers and save to a file
and then view the results later. I can give you pointers on this if
necessary.
As a check, I would certainly switch off the viewers and put a "print
step" in the time step loop just to check everything else is working
independent of the viewers.
Cheers
