Tutorial for Res2DInv Inversion with Topography

The program will automatically choose the optimum inversion parameters for a particular data set. Topographic effects can be modeled by using a distorted finite-element grid such that the surface of the grid matches the topography. It supports parallel calculations that significantly reduces the inversion time. A Pentium 4 (or compatible CPU) based microcomputer with at least 512 megabytes RAM and an 80-gigabyte hard-disk is recommended. Like RES2DINV, it is completely automatic and the user does not even have to supply a starting model. The RES3DINV program uses the smoothness-constrained least-squares inversion technique to produce a 3D model of the subsurface from the apparent resistivity data alone. The arrays supported include the pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, and Wenner-Schlumberger. This program is designed to invert data collected with a rectangular grid of electrodes. In areas with complex structures, there is no substitute for a fully 3D survey. The main limitation of such surveys is probably the assumption of a 2D structure. In areas where the geological structures are approximately two-dimensional (2D), conventional 2D electrical imaging surveys have been successfully used. Multi-core support with RES3DINV Basic, 256 Gb RAM ort with RES3DINV Professional Supports parallel calculations on Pentium 4 (and compatible) based computers Supports up to 5041 electrodes and 67500 data points on computers with 1GB RAM Supports smooth and sharp contrast inversions Supports exact and approximate least-squares optimization methods Now available as a combined package together with RES2DINV, the 2D Resistivity & IP inversion program.
