Interpex Ix1d V350 Instant

The version 3.50 release refined the user interface and processing engine, offering several key capabilities:

Even with robust software, users encounter challenges. Here’s how to solve them:

| Problem | Potential Cause | Solution in v350 | | :--- | :--- | :--- | | Inversion does not converge | Initial model too far from reality | Hit "Reset Model" and use the "half-space" automatic guess. Increase damping factor to 1.5. | | Equivalence oscillation | Too many layers | Reduce layer count. Use "Fixed Resistivity" for layers known from boreholes. | | Negative layer thickness | Overfitting noisy data | Apply data smoothing (3-point median filter). Re-run inversion with thickness constraints. | | Export file is garbled | Wrong delimiter | In Export Options, choose "Comma Delimited (CSV)" or "Tab Delimited" for Excel compatibility. | interpex ix1d v350

Click Invert > Automatic. The v350 engine iterates, reducing the RMS misfit. Watch the convergence plot—v350 provides real-time feedback. A typical final RMS under 5% is excellent for field data.

The primary purpose of IX1D is to take field data collected from the surface and calculate the likely layering of the earth underneath the measurement point. It operates on a 1D layered earth model, assuming the ground consists of horizontal layers of varying thickness and resistivity. The version 3

The software handles three main categories of data:

  • Frequency Domain EM (FDEM): It processes data from electromagnetic systems that measure in-phase and quadrature components. This includes support for popular instruments like: Frequency Domain EM (FDEM): It processes data from

  • Time Domain EM (TDEM): It interprets transient electromagnetic data, which is often used for deep sounding applications.

    • Leaking landfills create conductive plumes (high total dissolved solids). A baseline survey using IX1D v350 can track a plume’s lateral extent by comparing soundings upgradient and downgradient. The software’s sensitivity to thin conductive layers (e.g., 1 to 2 meters of leachate) is remarkable.
