This two approaches should deliver results close to each other.
They are both dealing with the same governing equation, the same boundary conditions, the same initial conditions.
The only difference is how they do the time integration. It is something like:
int[t_n-1, tn] f(t) dt = f(t_n-1)*dt for explicit
int[t_n-1, tn] f(t) dt = f(tn)*dt for implicit.
My conjecture is that if we are using the same spatial discretization, both approaches should have similar results. |
