Mesh refinement at measuring points of the three-dimensional layered geoelectric model. (a) is the mesh refinement at the measuring points of Mesh A. (b) is the mesh refinement at the measuring points of Mesh B1. (c) is the mesh refinement at the measuring points of Mesh B2. (d) is the mesh refinement at the measuring points of Mesh B340.
