Solver

See What’s New in the ERTLab Solver.

ERTLab Solver is the resistivity and IP inversion module that offers full three-dimensional topographical modeling and inversion. Its numerical core based on tetrahedral FEM allows the user to input complex topographic information and to invert data sets collected using surface, borehole and surface-to-hole array configurations.
