The paper describes an approximately characteristic finite element method for the solution of the time-dependent linear scalar convection-diffusion equation. The method is based on space-time elements approximately aligned with the characteristics in space-time. Attention is focused on implementation aspects: avoiding mesh tangling, efficient solution procedures and interpolation. Numerical results for some two-dimensional problems are given.
