convection_diffusion
A 1D convection-diffusion problem

convection_diffusion, a FENICS script which uses the finite element method to simulate the solution of a 1D convection-diffusion problem.

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

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