These optimizations can significantly reduce theĬalculation time for large data sets. Tutorial inversi res2dinv Pc#It is recommended that you use a PC with an Intel (rather than an AMD) CPU as the RES2DINV圆4 program is optimized for this type of CPU. You will need a microcomputer with a multi-core Intel CPU to run this program. This greatly increases the data and model size that can be processed. The program can access more than 4 GB GAM. ![]() Tutorial inversi res2dinv windows#Requirements : A PC with a 64-bit multi-core CPU, at least 4 GB RAM and a 64-bit version of Windows is required. On a modern multi-core PC, it will take less than a half a minute to invert the data set obtained from a survey with 100 electrodes. Besides normal surveys carried out with the electrodes on the ground surface, the program also supports aquatic and cross-borehole surveys.Ģ Computer system requirements This program is designed to run on microcomputers using the Windows XP/Vista/7/8 operating systems. You can process pseudosections with up to 16000 electrode positions and 100000 data points at a single time on a computer with 8 gigabytes (GB) of RAM using the Res2dinv圆4 program. In addition to these common arrays, the program even supports non-conventional arrays with an almost unlimited number of possible electrode configurations (Loke 2014). This program can be used for surveys using the Wenner, pole-pole, dipole-dipole, pole-dipole, Wenner-Schlumberger, multiple-gradient and equatorial dipole-dipole (rectangular) arrays. model together with the resistivity model using the complex resistivity method (Kenma et al. data is also present, the program will also generate an I.P. If topography is present, the program uses a distorted finite-element grid so that the surface of the grid matches the topography (Loke 2000). Sequence of measurements to build up a pseudosection using a computer controlled multi-electrode survey setup.Ī finite-difference or finite-element modeling subroutine is used to calculate the apparent resistivity values, and a non-linear smoothnessconstrained least-squares optimization technique is used to calculate the resistivity of the model blocks (deGroot-Hedlin and Constable 1990 Loke et al. However, the program can also handle data sets with a non-uniform electrode spacing.įigure 1. The survey is usually carried out with a system where the electrodes are arranged along a line with a constant spacing between adjacent electrodes. Many different multi-electrode systems have been developed over the past 25 years using different arrangements of the cables and measurement strategies (Loke 2014). Figure 1 shows an example of the electrodes arrangement and measurement sequence that can be used for a 2-D electrical imaging survey. It is a Windows based program that also supports multi-core CPUs. RES2DINV圆4 is a computer program that will automatically determine a two-dimensional (2-D) resistivity model for the subsurface for the data obtained from electrical imaging surveys (Dahlin 1996 Loke et al. Tutorial inversi res2dinv software#The Res2dinvx32圆4.pdf file has detailed instructions for using the software and should be used as the manual. 9ġ Introduction This is a very brief guide to help you in installing and getting started with the program. Typical display output showing the measured and calculated apparent resistivity pseudosections, and the inversion model section. Sequence of measurements to build up a pseudosection using a computer controlled multi-electrode survey setup.
