I have a basic question,
I have two reactors in contact with each other, both starting with the same initial conditions (equal amounts);
compound#1: solvent
Compund#2: A
compound#3: B
while in one of the reactors A is going to B and vice versa in the other reactor. I would assume that when I run the simulation, compounds A & B would diffuse ( the only physics added to the model being diffusion, no convection) and eventually reach a steady state. but when I run the simulation I get a negative mass fraction. how is that even possible?
