| Jul 1, 2022 at 14:11 | comment | added | nicholaswogan | I think the finite difference scheme I used is just not perfectly mass conserving. I need to be using a finite volume method, which will conserve mass perfectly. | |

| Jul 1, 2022 at 6:42 | comment | added | David Ketcheson | It seems like your $\Phi_{in}$ should be zero, since $a(x=0)=0$. So I would say that the problem you've stated is mathematically inconsistent. | |
