DiInSo is a software package for direct 3D and inverse 2D/3D electrical resistivity tomography (ERT) problems. It solves on direct current (DC) and is available for academic research as a 32-bit version.

The 32-bit version of the DiInSo software is free for academic research and has no limitations, except that the maximum amount of random access memory (RAM) that can be used by the application is limited to 2 Gigabytes. The 64-bit version of the program differs little from the 32-bit version, and it also comes with no limitations.
DiInSo allows you to use tetrahedral (or triangular in the 2D case) meshes when solving both direct and inverse ERT problems, which enables you to specify the geometries of areas of any complexity. A wide range of options for solving direct and inverse problems of ERT is available with DiInSo, allowing you to adjust the solution algorithm for specific purposes. The program also features built-in graphical visualizers that allow you to assess the results without leaving the application.
The software has a Windows-based interface, and its detailed documentation in English with examples make it easy to learn the program in a few days without being absorbed in complex theory. You can even convert input data from other ERT software systems to the DiInSo program format. Furthermore, the connectivity of the DiInSo software with well-proven Open Source projects allows for developing DiInSo at a high speed.
One of the distinct features of DiInSo is its ability to use many of its software options in automatic mode, making it ideal for novice users who have not yet learned all the program's features. Please note that this project is under development, so you might come across small, medium, large, and even critical errors. Nevertheless, the chief programmer, Arkadiy Marinenko, welcomes feedback and has provided his email address [email protected] for reporting errors or making suggestions to speed up the development process.
