Hi,
I am new to SfePy,
After installing everything, I run $ ./simple.py examples/diffusion/poisson.py as the tutorial says. The file cylinder.vtk is created. Then I run ./postproc.py cylinder.vtk but when I do so I get the next error:
*traits.trait_errors.TraitError: The 'current_scene' trait of an Engine
instance must be a Scene or None, but a value of
I can run mayavi first and then load the file cylinder.vtk but it shows the cylinder all blue and not as in the tutorial online.
Any help will be much appreciated!!
Cheers! Angel.

Could you post the whole error message (if there is), so that we can see the line numbers?
What is yout Mayavi version?

So you used the surface module to see something, right? The click on the file name and change "Point scalars name" from "node_groups" to "t" and you should see the temperature distribution. Does it help?
Cheers, r.

Well, I do not really understand this error message - it says the trait has to be Scene, and complains that it is enthought.mayavi.core.scene.Scene, which has been exactly the same thing...
What is yout Mayavi version?
4.2.1
... in versions of mayavi <= 4.0.0. I cannot debug this easily, as I have the lastest packaged version and installing mayavi's stack manually has been rather painful. I guess you downgrading for the moment is equally inconvenient for you, right? Maybe you could ask the Enthought guys directly (enthou...@enthought.com) what changed between 4.0.0 and 4.2.1 in handling the current_scene' trait of an Engine.

Ok, something works at least!

Buf! I would rather not downgrade mayavi now that something works at least :-) I will email Enthought directly and will post here their reply.

It does. Btw, is it the same thing? I mean, but drawing the file in this way, do I get the same info/result as with the postproc.py order?

Yes, postproc.py is just a way of quickly seeing the results by setting some reasonable default filters/modules for each dataset in a results file. You can get the same thing by setting up the VTK pipeline manually in the Mayavi GUI. It's just more mouse work :)
