Re: Fipy v1.1 installation problem?

Hi Hzh,

There were some windows installation problems that I fixed a month or two ago, but this hasn't been released yet.
It is probably worth releasing version 1.1.1 with new Windows instructions. Anyway, more below.

I installed FiPy v1.1 on windows XP following the instructions on your website.  One exception is that the link to http://download.enthought.com/enthought_python-2.3.5-1076-wx26-n238exe is not valid any more.  I downloaded
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:-

Anyway, here are the new Windows installation instructions. Important bit for you is the bit about enthought python, which has now changed.
However, I am not sure if this has anything to do with the problem you have below, I will have to investigate and get back to you.

===========================
Simple Windows Installation
===========================

These instructions are for the `Windows XP`_ and `Windows 2000`_
platforms. Please see the more general |INSTALLATION-txt| for detailed
installation instructions.  These instructions are not the only way to
set up |FiPy| on a Windows OS but represent the most expedient way
from our experience to have a usable installation up and running.

.. note::

   These steps require downloading installation ``.exe`` binary files from
   various web sites.  When given the choice to ``run`` (``open``) or
   ``save`` these files it is best to simply choose ``run`` (``open``).

.. include:: utils/include.txt

.. |INSTALLATION-txt| replace:: |htmlINSTALL| |latexINSTALL|





We recommend the use of Enthought Python. This version of Python has
some of the packages for |FiPy| already included. Download and install
the latest version.

Pysparse
--------


Download and install the latest version of PySparse for Windows
(pysparse-x.y.z.win32-py2.X.exe). Be sure to select the version
compiled with the correct version of Python to match the Enthought
installation.


|FiPy|
------


Download and unpack the zip file (``FiPy-x.y.win32.zip``).  Run the
|FiPy| installer ``FiPy-x.y.win32.exe``, which should be in the base
``FiPy-x.y`` directory.

Optional Packages
=================

Gmsh
----


If you wish to run examples that have unstructured meshes, it is
necessary to install Gmsh. Download and unpack the latest version of
Gmsh for Windows. Open the unpacked folder with a browser and copy the
``gmsh.exe`` file to ``C:\Python2X``.

.. note::

   This is a required package for superfill examples.

PyVTK
-----


If you wish to use Mayavi, PyVTK is a requirement.  Download and
install the latest version from the |FiPy| downloads page
(``PyVTK-x.y.z.win32.exe``).

.. note::

   This is a required package for superfill examples.

Mayavi
------

Mayavi comes with Enthought Python, so no installation steps need to
be taken. However, there seems to be a file out of place. In order to
make Mayavi work correctly, open the
``C:\Python2X\Lib\site-packages\vtk_python\`` directory in a browser
and move ``vtkRenderingPythonTkWidgets.dll`` to the ``C:\Python2X\``
directory.

.. note::

   This is a required step for superfill examples.

Using |FiPy| on Windows
=======================

For those that are averse to the Windows command line, the IDLE_
environment is recommended. IDLE_ is packaged with Enthought Python
and will appear in the Windows Program menu after installation.

Interactive Viewing
-------------------

Some versions of Enthought Python have been known to have problems
with interactive viewing. If this turns out to be the case, follow
these instructions:

   - Click on ``Start``
   - Click on ``Programs``
   - Click on ``Python 2.X (Enthought Edition)``
   - Right click on ``IDLE (Python GUI)`` and click on ``Create Shortcut`` which creates ``IDLE (Python GUI)(2)``
   - Right click on ``IDLE (Python GUI)(2)``
   - Click on properties
   - Add the ``-n`` option to ``Target`` being sure to leave a space after the last quote and before ``-n``
   - Drag and drop ``IDLE (Python GUI)(2)`` to the desktop to create an icon.

Import a module and view the results
------------------------------------

You can use the IDLE_ file browser to open the examples and run the
module.

    - Click on ``File``
    - Click on ``Open``
    - Open ``C:\Path\To\Base\FiPy\directory\examples\diffusion\steadyState\mesh50x50\input.py``

This will open an editor, press the F5 key to run the example.
A Matplotlib viewer should appear with rainbow stripes.

Another way to use |FiPy| examples is to import the example file and
then run any functionality it may have. For example at the IDLE_
command line run the following code:

    >>> import sys
    >>> sys.path.append('C://Path//To//Base//FiPy//Directory')
    >>> from examples.levelSet.electroChem.inputGold import runGold
    >>> runGold(numberOfSteps = 100)

If you have installed the optional packages, a MayaVi viewer should
appear with a trench filling simulation.

As for this problem, I am about to look into it.

Cheers


Thanks very much for your time!
