Relative difference in the electrical field strength magnitude—Almi5.

Heatmap of the relative difference in the magnitude of the electrical field strength between OpenFOAM and SimNIBS in all three electrode configurations. A red color indicates a higher electrical field strength in the OpenFOAM result whereas blue indicates a higher value in the SimNIBS result. Histograms depict differences in percent of all tetrahedra within the gray matter mesh compartment.
