Hi again!
I have taken the isympy code (interactive sympy shell based on ipython), tweaked it, and called isfepy  the interactive sfepy shell. It is still very preliminary, but it opens new possibilities of how sfepy could be deployed, and even now it is usable for the basic stuff, like:
In [1]: pb, vec, data = pde_solve('input/poisson.py') In [2]: view = Viewer(pb.get_output_name()) In [3]: view()
[1] solves a Poisson equation in 3D by the finite elements, [2] constructs a mayavi2 viewer, and [3] displays the results using the mayavi's mlab.show(). Of course, [1] should work for other input files too.
In this way one can quickly run simple problem inputs and view the results immediately.
Could you try it, please, when you have some spare moments? The plotting requires mayavi2 (at least 3.1.0), but it is not mandatory  only the step [3] will do nothing.
cheers, r.

Definitely. Here is the output on Ubuntu Jaunty:

So things work, but the warnings are annoying.

Yes, they suck. The first warning is due to Python 2.6, the second one is a scipy warning  I can fix the latter, but do not know how to fix the first one.

ok, I am just getting stupid as time goes on... both can be fixed, of course.

I fixed the graphics on my computer and the mayavi works now. Awesome. I am seeing some black cross in the mayavi window (see the png attached), is it intended?

it is 't'  the name of the variable plotted  try other examples :)

Ah, I see. Yeah, that works well.
