fenics installer for 64bit windows available?

Asked by Arnd Flatten

Is there an installer for windows-64bit available?

I used the executable fenics-1.0.0-mingw32.exe and this installed fenics without any problem on my window-system (windows 7 64bit), but I seem to not be able to use the full system memory for running a 'large' model...

You also say on your download-page for windows, that the binary "does not currently include PETSc or Trilinos, which makes it unsuitable for solving any real problems". So, the uBLAS linear_algebra_backend is not sufficient for large problems? How can I then include these packages in my windows-fenics program?

Thank you very much ahead,
Arnd

The problem is that both PETSc and Trilinos are difficult to build and
distribute on Windows. So we provide a stripped-down version for
Windows that uses uBLAS for linear algebra. This will get you far, but
you won't be able to run in parallel.

My recommendation would be to install Ubuntu or some other GNU/Linux
distro. It's much better suited for computing.
