Hello,
I am just starting out with FEniCS and was trying out the Python Cahn-Hilliard
example under 'dolfin-1.4.0/demo/documented/cahn-hilliard/python’. However, I
get the following error. Any thoughts on this issue? What mistake am I making?
The detailed error is copied below. I have FEniCS built from source and running
on an Ubuntu 12.04 machine. The SWIG version in the machine is 2.0.4.
Many thanks,
Aniruddha
