FEniCS is a programming environment so you need to write a program (in
Python or C++) that solves your problem.

If you want to simulate FSI, you could try the FSI code which is
available in the CBC.Solve package. It's currently in development and
we have not yet released a stable version. Download the package from here:

  https://launchpad.net/cbc.solve

Then look inside the directory sandbox/fsi

We expect to polish the code and make a release within a month or so.

Thank you I will look into CBC.Solve it looks very promising.

I plan to write programs in Python. I have one final question for now regarding this. I am attempting to run the demo.py in the command shell by typing 'python demo.py' however the file is not located in the correct sub-folder. Which folder should I be saving demo files and additional programs I create?

Thank you again.

You should save them in the same directory as where you type 'python
demo.py' or, equivalently, change the directory to where that file is
stored before you run the command.
