Once I do run it, how does it output the output of the program? do I need to compile demo.py before running it? Your help would be appreciated.

Type this in the command prompt and then press enter:

  python demo.py

Then the following will happen:

1. You will see some text being printed
2. You will see a plot of the solution in a separate window
3. The solution will be stored to a .pvd file which you can
   visualize in for example ParaView or MayaVi

Good luck
