Furthermore,​ each of the compartments is described by a conductivity. + In case of the BEM, the volume conduction model consists of one or multiple homogenous and isotropic compartments. The compartment boundaries are closed and non-intersecting surfaces that are described by triangulated meshes. Furthermore,​ each of the compartments is described by a conductivity. To make the highest quality BEM volume conduction model, FieldTrip offers a number of functions to manipulate these three classes of geometrical data. If we summarize the geometrical data as **anatomy**,​ **segmentation** and **mesh**, then we can consider functions that take one type of geometrical data as input, and return the same or another type.
