The recovered model of scenario two for a 1 m target radius situated at 3 m depth applying the inversion freeware: a pyGIMLi, b BERT, c ResIPy, and d SimPEG. The broken circles show the actual targets; the left for conductive while the right for resistive target. pyGIMLi, BERT, and ResIPy use unstructured triangular mesh, while SimPEG implements tensor mesh
