Subject: Re: Getting FiPy working on Windows XP
Hi Daniel and Jon,
Thanks for your feedback. I have had some progress on executing the
single examples. Although I had initially used the IDLE GUI, I recently
had tried other ways. But returning to the
IDLE GUI has worked. I saw "rainbow" color plots when executing (F5 key)
for both
'C:\Python23\FiPy-1.1
\examples\diffusion\steadyState\mesh50x50\input.py', and
'C:\Python23\FiPy-1.1\examples\diffusion\mesh20x20.py' (here I
get a prompt on the Python shell after the first rainbow plot, and
hitting ENTER produces a second plot).
Trying execution of Jon's suggested example 'C:\Python23\FiPy-1.1
\examples\diffusion\mesh1D.py' produced no plot and this error message:
Traceback (most recent call last):
File "C:\Python23\FiPy-1.1\examples\diffusion\mesh1D.py", line 779,
in ?
exec(fipy.tests.doctestPlus._getScript())
File "<string>", line 38, in ?
File "C:\Python23\Lib\site-packages\fipy\viewers\__init__.py", line
88, in make
raise ImportError, "Failed to import a viewer: %s" % str(errors)
ImportError: Failed to import a viewer: ['gistViewer: cannot import
name GistViewer', 'gnuplotViewer: cannot import name GnuplotViewer',
'matplotlibViewer: cannot import name MatplotlibViewer',
'mayaviViewer: Mayavi does not display useful 1D data', "multiViewer:
'module' object has no attribute 'make'", "tsvViewer: 'module' object
has no attribute 'make'", "viewer: 'module' object has no attribute
'make'"]
Thanks for your help! Now I feel like I can proceed to code my
problem and give it a try.
It's OK with me if you post my email inquiry to users.

Hi Terry,
Thanks for your interest. Would you mind if I forward this email and the
reply to
our mailing list so that it is archived?
Hopefully, FiPy will help you with your work and we are happy to
provide assistance where
we can.
As far as the tests in the examples directory are concerned, you probably
just need to set
the PYTHONPATH to point at 'C:\Python23\FiPy-1.1' then the tests should be
able to
see the required modules.
You also mentioned that when you run the examples you are not seeing any
plots on the screen.
What happens when you open
C:\Python23\examples\diffusion\steadyState\mesh50x50\input.py
in IDLE and then run the module (press F5)? Is it that nothing shows up at
all or do you get an error message?
If it is that nothing shows up at all, try the following command at the
IDLE command line (assuming you have Matplotlib
installed):
>>> import pylab
>>> pylab.plot((1,2,3))
>>> pylab.show()
Do you get something on the screen?
Cheers
Daniel Wheeler
Gentlemen,
I'm a physicist trying to solve the heat conduction PDE in (z,t)
for an
application we have. The problem has a time-dependent heat source
and the
possibility of a temperature-dependent thermal
conductivity in one film in a stack. Of course, I have abrupt
discontinuities between the different films in the stack (at least in
the
model). To date, I have run into seemingly insurmountable
difficulties in
getting toward a solution in Mathcad, Mathematica, and MATLAB.
Then I
came across FiPy on the web, and it looks more capable, so I was
encouraged. However, after attempting the Windows installation, and
running some of the tests, I cannot seem to get past a string of
errors,
and I have not yet seen any plot of a result in any example. Here
is a
recent log of the errors from running 'test.py' in
'C:\Python23\FiPy-1.1
\examples' (See attached file: Python_test_errors3.doc) . I can't
really
decipher it, but I suspect that FiPy is having some trouble locating
files.
Here is a screen shot of the main Python directory on my C drive
where all
this stuff is placed (See attached file: Python23_directory.gif) .
I'm not necessarily a computer specialist - I'm a modeler. I
tried to
follow the order and instructions for installation from the site
'path' in the environmental variables was a little vague to me, so
all that
I did manually was set the Windows XP environmental variable / system
variable PYTHONPATH to 'C:\Python23'.
I notice that the installation
procedure apparently added automatically a string
'C:\Python23;C:\Python23\Scripts;C:\Python23\Enthought\MingW\bin;C:\Python23\Enthought\SWIG-1.3.24'
to the Path system variable. Perhaps my environment is still not
completely set up.
I am eager to get on to solving a PDE if I can get around the
installation hiccoughs. Thanks in advance for any suggestions you
might
offer. I am reachable at the phone below, or of course at this email
address. I might be able to link up on Webex or NetMeeting if
desired.
