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.
: You can create cross-sectional profiles by selecting soundings on the map via point-and-click or polygon selection. Visual Output interpex ix1d v350
Alluvial basin in Rajasthan, India Goal: Locate a fresh water aquifer under 40 m of clayey sand Method: 10 VES soundings with AB/2 from 1.5 m to 300 m Click Invert > Automatic
[Import Raw Sounding Data] │ ▼ [Perform Occam Smooth Inversion] ──► (Identifies continuous depth trends) │ ▼ [Design Layered Model (Marquardt)] ──► (Extracts distinct geologic boundaries) │ ▼ [Run Equivalence Analysis] ──► (Validates non-uniqueness & reliability) Step 1: Smooth Inversion (Occam's Method) A typical final RMS under 5% is excellent for field data
: A critical step to check the "uniqueness" of your model. It determines the range of thicknesses and resistivities that could produce the same curve fit. Key Features for Version 3.50
: Handles frequency-domain EM (In-phase and Quadrature), Magnetotellurics (MT), and Transient EM (TEM). Conductivity Measurements
