To find the best-fitting model, IX1D uses industry-standard, nonlinear least-squares curve fitting techniques. The software provides flexibility by offering two primary inversion methods:
Older versions suffered from a dated, clunky interface. v350 features a cleaner layout, dockable windows, and improved graphics rendering. The resistivity pseudo-section display now supports real-time zooming and panning. interpex ix1d v350
However, the IX1D V350 is not without limitations. Its primary constraint is its inherent 1D assumption: it presumes the subsurface is composed of horizontal, laterally infinite layers. In areas with steeply dipping beds, boulders, or significant 3D structures (like a narrow dike), the inversion can produce misleading or non-unique results. Furthermore, the interface, while functional and efficient, retains a distinctly late-1990s aesthetic, lacking the interactive 3D visualization common in modern software like Res2DInv or Voxler. For a generation of students raised on touchscreens, the dialog-box-driven workflow can feel initially archaic. To find the best-fitting model, IX1D uses industry-standard,
