Hi Luke,
I just wanted to let you know that setting a different initial concentration for each domain worked. At the beginning it returned a singularity error because the difference between concentrations at each domain was too big, resulting in a too large initial step size for the solver. I used a smoothed step function and it worked fine.
Thank you again.
