The bidomain action potential at the slab centre (point P9) for (dotted line) and (continuos line) and with mesh mesh resolution cm (red line), cm (green line). The action potentials for the full duration of the simulation are shown on the left. On the right the differences between and are shown by zooming in on the AP upstroke (15–25 ms).
