DOLFIN

Cannot plot after new installation

Asked by Jack

After installing, on running the Hyperelasticity demo, plotting fails. This is the error:

Plotting u (a function), press 'q' to continue...
Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/viper", line 225, in <module>

    p = __main(infile, lutfile, mode, title)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/viper", line 152, in __main
    return _plot_mesh(infile, lutfile, mode, title)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/viper", line 116, in _plot_mesh
    import dolfin
ImportError: No module named dolfin
*** Warning: Unable to plot.

Did you source the file <CMAKE_INSTALL_PREFIX>/share/dolfin/dolfin.conf after installing DOLFIN as noted in the post-install message? How did you install FEniCS? Did you use Dorsal? If not, I will suggest that you try that.

Hi Johannes

Yes, I did. I installed it via Dorsal except for DOLFIN, which I had to make manually because boost.thread wasn't being found.

 Somehow your dolfin python module can either not be found or loaded, so
can you check
1. your PYTHONPATH variable (what is it?) It should
contain to the <INSTALLATIONPATH>/lib/python2.6/site-packages (or
python2.x depending on your
version)
2. what happens if you import dolfin within a running interactive python
instance?
