Simulating Cardiac Electrophysiology Using Unstructured All-Hexahedra Spectral Elements

Figure 16

Space-refinement convergence experiments for monodomain action potential in the human heart subvolume. Continuos lines indicate FEM solution with mesh resolution cm (black), cm (orange), cm (green), and cm (red). Dotted line denote SEM solutions with and spatial resolution cm (blue). The action potentials for the full duration of the simulation are shown on the left. On the right the AP upstroke (8–11 ms) is shown for the same range of mesh refinements.
