I have run the "separation through dialysis" problem. It worked fine but whenever I just unchecked the convection term and disabled the corresponding boundary conditions to get only diffusion driven process, following error message is showing: The relative error (22) is greater than the relative tolerance.
Returned solution is not converged.

Sometimes the value of relative error in the brackets are changing. I don't undestand them.

How to solve this problem ?
