Numerical simulation of multilayer grounding grids in a user-friendly open-source CAD interface
In this paper we present TOTBEM: a freeware application for the in-house computer aided design and analysis of grounding grids. The actual version of the software is available for testing purposes (and also use) at no cost and can be run on any basic personal computer (as of 2011) with no special requirements. The distribution kit consists in a single ISO bootable image file that can be freely downloaded from the Internet and copied into a DVD or a USB flash memory drive. The application runs on the Ubuntu 10.04 (Lucid Lynx) LTS release of Linux and can be easily started by just booting the system from the live DVD/USB that contains the downloaded file. This operation does not modify the native operative system nor installs any software in the computer, but the application is still fully operational while the live DVD/USB is taking control. The pre- and postprocessing engines of the application have been built on top of the open source SALOME platform toolkit. On the other hand, the analysis part of the code is based on the Boundary Element Method (BEM). The implemented BEM formulation (that has been presented by the authors in previous publications) is suitable for computing the equivalent resistance and the step and touch voltage in most large electrical overground substations with a grounding grid embedded in a single- or multilayer stratified soil.
