Stable Version of DOLFIN (0.9.9) for Windows

Sorry, the Windows (and Mac) installer is currently only available with the development version of DOLFIN. However, the installer is not up-to-date so your problem might have been fixed in the latest code. I don't know but I can rebuild the installer with the latest development packages and you can then check to see if your problem is resolved. I will let you know when the new installer is ready for download.

Dear Johannes,

Thank you very much for the quick response and the offer to rebuild.
Dr. Rognes specified version 0.9.9 and thus I hope you are able to
rebuild with this version. Thanks!

All the best,
Robert

Hi Robert,

DOLFIN 0.9.9 is now available from this Windows installer:

http://www.fenicsproject.org/pub/software/fenics/fenics-10.09-mingw32.exe

Dear Johannes,

Thank you so much! That'll help me get things moving again and I will begin testing it today.

I have a second question regarding Mac, although it is not as urgent as the Windows question. We will soon need to use Mac OSX Snow Leopard for development and I was hoping that you could put a Mac version of the installer up for download as well.

Many thanks again,

Robert

Yes, I will look at making a package for Mac with DOLFIN 0.9.9 as well.

Hi Johannes,

Regarding the new v0.9.9 build of DOLFIN, I am able to successfully run the example program located in \share\dolfin\demo\pde\navier-stokes\python\demo.py

However, when attempting to run the adaptive example program located here,

 \share\dolfin\demo\undocumented\adaptive-pde\navier-stokes.py

... I receive the exception message below. What might be causing this?

The mesh is refined in the adaptive loop, and various functions on the
original mesh are transferred to the refined mesh. However in this
case, the functions end up being evaluated at points that seem (due to
rounding errors) to lie outside the mesh. This will normally give an
error, but specifying

         parameters["allow_extrapolation"] = True

allows an extrapolation to a "closest point in mesh". The finding of
the closest point makes use of the external library CGAL, which I
guess is not included in the windows installation.

Thank you both very much for the quick responses. I am glad to see that the original error has been remedied. The new exception thrown by DOLFIN now makes much more sense now. Thank you Dr. Rognes!

What would be the best way to proceed from here and get past the issue of the missing CGAL? My simple goal is to run the adaptive example that is located in the undocumented demos.

Many thanks once more,

Robert

Robert,

I will look at the issue with the missing CGAL tomorrow and rebuild the installer when I find the error. I expect it will be relatively easy.

Robert,

A new package has been uploaded with DOLFIN 0.9.9 built with support for CGAL:

  http://www.fenicsproject.org/pub/software/fenics/fenics-10.09-mingw32.exe

Johannes,

All seems to be working well now. Thank you for the Windows rebuild and will be looking forward to the Mac build sometime soon.

Sincerely,

Robert

Excellent!

Hi Robert,

There is now a FEniCS installer with DOLFIN 0.9.9 for OS X 10.6 available from here:
