Quantitative comparisons of forward problems in MEEG

Abstract: This document,gives comparisons between several methods that solve the forward problem in MEEG by comparing their precision on a 3-layer spherical model. These methods are based on,nite elements which either use surfacic meshes with triangles, volumic meshes with tetrahedra, or implicit ele- ments deduced from levelsets.
