tutorial not up to date with release 1.1

[Michele Zaffalon]

The tutorial (and the FEniCS book) refers to release 1.0:

1) The examples use UnitSquare, Rectangle... to mesh, which is deprecated in release 1.1.

2) In the section Examining the Solution the ordering of the degrees of freedom is not that of the nodes (see http://fenicsproject.org/qa/207/how-to-interpolate-data-at-vertices-of-3d-cells and http://fenicsproject.org/qa/465/interpolate-function-given-matrix-on-finite-element-basis).

3) In the page http://fenicsproject.org/documentation/tutorial/index.html, the tarball fenics_tutorial_examples.tar.gz does not contain the transient examples.

First encounter with FEniCS: compilation error on the very first tutorial :( I do hope that this issue gets addressed.

I filed a bug report, on what appeared to be the wrong project site (dolfin) https://bitbucket.org/fenics-project/dolfin/issue/332/tutorials-produces-error-warnings-in

In short, I found that you get different error messages depending on if you run Ubuntu 12.04 (error x2) or 14.04 (one warning, one error). Moreover, I'm still at a loss on how to get the second tutorial working. Changing UnitCircle to CircleMesh, still produces errors in Ubutntu 14.04.

The tutorial examples, updated to work with the latest DOLFIN, can be found in the DOLFIN source code:

test/unit/book/python

(see also https://bitbucket.org/fenics-project/dolfin/src/222dea498ec8b1872d6850845c6f7473048a5a50/test/unit/book/python/?at=master)

Issue #11 was marked as a duplicate of this issue.

Recurring all the time on fenics-support list:

python d1_p2D.py
NameError: name 'UnitSquare' is not defined

[Prof Garth Wells]

Solution agreed in dev meeting is to remove tutorial from web page.

[Martin Sandve Alnæs]

@logg is working with @hplbit on upgrading the tutorial.

How do we make it sustainable?

How do we make it sustainable?

1. testing it regularly
2. including it into DOLFIN repository?

[Prof Garth Wells]

Added note on web page the tutorial and book are for 1.0, and that demos are the best reference for the current release.
