TVD schem coupled with Crank-Nicolson
 
Hi,

I am going to use a TVD scheme for my scalar descretazation. Since I want to use Crank-Nicolson (C_N) method for time advancement, I am a bit confused what should I do for the deferred correction terms of the old time step?

As you now in TVD we have some contribution from the old time step as the deferred correction to use in the source term.

Now, what should I do for the contribution of the old time step coming from C-N? should I use old of old?

Your comment is appreciated.
