OPTUM GX vs. OPTUM G2 & optum G3
OPTUM GX is the next generation of our geotechnical analysis tools — built on the proven OBFEM framework from OPTUM G2 and OPTUM G3. OPTUM GX marks a significant advancement in geotechnical analysis — bringing 2D and 3D capabilities together in one unified software.
With a fully redesigned reporting module, built-in Python scripting, and support for custom plugins, OPTUM GX significantly reduces manual work and streamlines even the most complex workflows. The result? Faster project delivery, fewer repetitive tasks, and more time for critical engineering decisions.
OPTUM GX isn’t a replacement for the trusted OPTUM G2 or G3 — it’s an extension that builds upon their strengths.

What’s New, What’s Better, and Why It Matters
Work in 2D and 3D in one software
OPTUM GX introduces a groundbreaking feature: the ability to seamlessly switch between 2D and 3D modeling within a fully integrated environment. This is a first in geotechnical engineering and provides users with unparalleled flexibility to assess their projects with real-world complexity.
2D modeling offers faster computations, while 3D reduces assumptions for more precise analysis. With GX, users can easily start in 2D, extrude into 3D, or extract 2D sections from complex 3D models for detailed evaluation. This unique capability streamlines workflows, enhances accuracy, and ensures better decision-making—setting a new standard in geotechnical simulation.

Python Scripting
Tired of spending hours setting up geotechnical models with minor parameter changes? The new Python-integrated GX plugin is here to eliminate repetitive manual work and streamline your workflow like never before.
With this powerful new feature, you can automate project setups, modify models in seconds, and focus on engineering instead of data entry. You benefit from drastically reduced setup and analysis time, the ability to instantly update and rerun models for seamless scenario testing, and minimized errors through automated configurations that ensure consistency and accuracy.
For advanced users, the plugin includes the pre-built SpooGX scripting framework and also supports custom scripting in JavaScript.
improved Interface
High-quality documentation
OPTUM GX delivers a major upgrade in reporting and documentation compared to OPTUM G2, eliminating the need for time-consuming manual adjustments. With fully automated, customizable reports, engineers can quickly generate professional documentation, including geometry sketches, material data, stage sequencing, and key results such as deformation plots and collapse mechanisms. Reports are instantly available in PDF format, saving valuable time and ensuring a seamless workflow — no more DIY reporting.
