Navier Stokes Flow in 2D Eccentric Annulus

annulus_flow, a FENICS script which models the flow of a fluid, governed by the time dependent Navier-Stokes equations, in a 2D eccentric annulus.

Note that I have installed FENICS using Docker, and so to run this script I issue the commands:

1. cd $HOME/fenicsproject/annulus_flow
2. fenicsproject run
3. python3 annulus_flow.py
4. exit
