Profiles of the non-electrostatic potential U (left) and the Péclet number (right) for the system investigated in Experiment 3. The schematics of the system is shown in Fig. 2(b). Both profiles were computed along a line parallel to the z-axis and passing through x = y = 1.5 nm. In these profiles, the surface of the nanopore, which separates the solvent region from the membrane, is located at z = 2 nm. The sharp repulsive gradients in the potential U cause spurious modes in the Galerkin approximation.
