Interpex has migrated its development environment from Microsoft Visual Studio 6 and Compaq Visual Fortran to . This change improves speed—especially on Intel processors—and ensures compatibility with modern Windows operating systems.
Beyond its mathematical core, the software’s practical utility is enhanced by several key features. The “forward modeling” mode is exceptional for educational purposes and hypothesis testing, allowing users to build synthetic geological models (e.g., a resistive layer over a conductive aquifer) and instantly view the resulting apparent resistivity curve. Critically, the V350 version introduced advanced capabilities like the handling of induced polarization (IP) effects, allowing for the joint interpretation of resistivity and chargeability data—a powerful combination for mineral exploration. The ability to import and export data in multiple formats, alongside a manual "picking" routine to estimate asymptotic resistivities, streamlines what would otherwise be tedious calculations.

: You can either predict what a graph should look like based on a model (forward) or let the software calculate the best-fitting model for your field data (inverse).
Results export as text, images (BMP/PNG), or directly to Interpex’s IX1Dv2 format for reporting.

: At first, the software showed a simple two-layer model. It didn't match the field data at all.
). This is ideal for shallow instruments like Geonics EM-31, EM-34, or EM-38 units.
Field data often contains noise caused by poor electrode contact, cultural interference (like fences or pipelines), or instrument errors. IX1D allows users to visually inspect the data curve and "mask" (ignore) outlier data points without permanently deleting them from the file. Step 3: Initial Model Creation cultural interference (like fences or pipelines)
Before running an inversion, the user must provide a starting model. This can be done automatically by the software using a smooth Occam approach, or manually by estimating the number of geological layers based on local borehole data. Step 4: Running the Inversion
