I didn't understand what you meant by a > "ramp in time". Could you please elaborate? Since you are using a low order method in time, I am just wondering if the solution is linear in time. This is one way to have the exact solution at each time step and it could explain why the error is zero (assuming that there is no spatial error)

Good catch!! Patch incoming.
