Grid diagram of the cross section of the three-dimensional layered geoelectric model. (a) is the cross section of Mesh A. The red part represents the triangular prism mesh, and the remaining part represents the tetrahedral mesh. (b) is the cross section of Mesh B1. (c) is the cross section of Mesh B2. (d) is the cross section of Mesh B340.
