Interpex Ix1d V350 Fixed
Based on the likely typo in your request, you are referring to , a legendary piece of software used in geophysics for subsurface modeling.
Bottom line Interpex IX1D V3.50 remains a practical, technically sound choice for anyone committed to 1‑D geophysical sounding work: compact, feature‑complete for its niche, and dependable — especially when interpretive clarity and inversion control matter more than modern UI bells and whistles.
Interpex does not list public prices. Expect ~$800–1200 USD for a single-user license (perpetual). Maintenance (updates + support) is separate (~$200/year). A free demo is available (limited to 5 layers, no export). Competitors: (less common), IPI2Win (free, Russian, but buggy), ZondRes1D (~$400, modern UI).
v350 allows you to fix layer thicknesses or resistivities, add smoothness constraints, and use “Occam’s inversion” for smoother models—critical when geology suggests gradational contacts rather than sharp boundaries.
: Supports Frequency-Domain (Horizontal/Vertical Coplanar, Vertical Coaxial) and Transient EM (TEM) configurations such as central, fixed, or coincident loops. Inversion Options : Offers both (1 to 10 layers) and (10 to 100 layers) inversion types. Forward Modeling interpex ix1d v350
is a professional geophysical software application specialized in 1D inversion and interpretation of resistivity, induced polarization (IP), magnetotelluric (MT), and electromagnetic (EM) sounding data. Developed by Interpex Limited , it is a widely used tool in environmental, geotechnical, and groundwater exploration. Core Capabilities
The software allows a geophysicist to overlay a Magnetic survey on top of a Resistivity sounding. This "Grand Slam" approach allows the user to correlate different physical properties to solve a single puzzle. For example, “This area has high resistivity (hard rock) AND a magnetic anomaly (iron content), so we must be looking at a basalt dyke.”
) using standard low-induction-number systems like the Geonics EM-31, EM-34, and EM-38.
The Interpex IX1D V350 offers a range of benefits to users, including: Based on the likely typo in your request,

, a cornerstone for processing and inverting electrical sounding data. Whether you're hunting for groundwater or mapping geotechnical layers, here is why this software remains a "solid" choice for your toolkit. What is Interpex IX1D v3? At its core, Interpex IX1D v3 induced polarization (IP)
MT forward modeling using plane wave or user-defined segmented wire sources. Interactive Editing
Handles measurements in PFE, chargeability (msec), or phase (mrad).
The software is remarkably versatile, supporting a wide array of electrical and electromagnetic methods: DC Resistivity & IP : Supports standard arrays like Schlumberger Dipole-dipole . You can model resistivity alone or include Induced Polarization (IP) data in terms of chargeability or phase. Electromagnetics (EM)
Interpex IX1D is a 1D interpretation software package designed for a variety of geophysical methods. It specializes in of resistivity, induced polarization (IP), and electromagnetic (EM) data.
