<div>Thanks Barry, I attach the terminal outputs. From my reading, it seems like everything converged alright, no? Usually I get an error message when the linear or snes solver doesn't converge. </div>

<div>By the way, I don't think it should matter but for your reference I am doing an operator split method in FEniCS where I am alternating between solving two system until their solution vectors stop changing between iterations. </div>
