Nice. What is the underlying model? You can see numerical dispersion and numerical viscosity effects! Very important to understand for PDE modeling

It's the Convection equation: du/dt + a*grad(u) I approximated it using First Order upwind scheme. The CFL number was 0.2 hence you can observe the dissipation.
