Regarding the error when you run "C:\FiPy\EXEs\FiPy-1.1.win32\FiPy-1.1\examples\diffusion\mesh1D.py".

Unfortunately, I can't seem to reproduce it. I am using a version of enthon that is based on Python 2.4. This

could possibly cause some differences, but I am not sure.

I did try to use Python 2.4, but following the installation instructions (for Windows) on your website, I found that the installation of one package (forgot which one, maybe matplotlib) requires Python version 2.3.  Therefore, I uninstalled 2.4 and installed 2.3 instead.

The Windows instructions you probably followed require you to install matplotlib, but the version

of enthon you installed may have had matplotlib included. This could be a possible cause of conflicts.

Do you think this could be the case?

I literally followed the instructions on your website and yes I installed matplotlib.  w.r.t your question here, I am not sure...

Can you run and "C:\FiPy\EXEs\FiPy-1.1.win32\FiPy-1.1\examples\diffusion\steadyState\mesh50x50\input.py".

Tell me what happens.

Program successfully finished.

If you run "C:\FiPy\EXEs\FiPy-1.1.win32\FiPy-1.1\examples\convection\peclet.py" what happens?

Traceback (most recent call last):
  File "C:\FiPy\FiPy-1.1.win32\FiPy-1.1\examples\convection\peclet.py", line 110, in ?
    exec(fipy.tests.doctestPlus._getScript())
  File "<string>", line 16, 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: float division', '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'"]

Take a look at what happens with these examples. You could also start over with the latest python 2.4 version of enthon

and use the instructions I posted in the previous email.

Also, we can go through the process of debugging the error message, but I thought I would check a few things before

getting our hands dirty.

Cheers

Release 0.9.9 (2006-09-14 20:52)
Python 2.3.5 - Windows	enthon-python2.3-0.9.9.exe	113 MB

instead.  I am wondering why I got the following errors when I tried to run the first example in the manual:-

Thanks very much for your time!
