Can't import UnitSquare

Question

I am trying to run the first example of the tutorial but fails,
turns out that does not import

>>> from dolfin import UnitSquare
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError: cannot import name UnitSquare

The installation was done in ubuntu with

 sudo add-apt-repository ppa:fenics-packages/fenics
sudo apt-get update
sudo apt-get install fenics
sudo apt-get dist-upgrade

Maybe is nedded some package

Answer 1

A bunch of mesh classes were renamed in FEniCS version 1.1 in order to avoid name clashes with similar geometry classes (see "Interface Changes" in the Release Notes: http://libelemental.org/releases/1.1/index.html). I'm surprised that this has not been changed in the tutorial yet, but if you replace UnitSquare with UnitSquareMesh is should work.

thanks, it worked.
