OPTUM GX
Geotechnical analysis software
OPTUM GX is the first geotechnical FEM tool on the market that allows modelling in both 2D (plane strain/axisymmetry) and 3D within the same program. Developed with one clear purpose: to save engineers’ time. Tailored for geotechnical professionals, it offers a comprehensive suite of material models and analyses, making it ideal for geotechnical modelling, routine engineering calculations, and advanced geotechnical design. Additionally, the built-in Python scripting development environment enables users to access specialized applications and quickly develop custom plugins. The program also features a state-of-the-art report generation module, facilitating swift and seamless documentation of analysis results and designs.
Key Features
Work in 2D & 3D seamlessly
Accurate behaviour, improved predictive power.
Fast reporting & documentation
One Click 2D –> 3D Conversion
Many geotechnical problems can largely be considered 2D, but certain features make a purely 2D approximation inaccurate, for example, a pile-reinforced slope or a square foundation on a retaining wall. While the overall geometry can often be treated as 2D, these additional elements — such as pile rows and square foundations — make the problems inherently 3D.
To achieve the most accurate representation of reality and ensure reliable results, 3D modeling is essential.
With OPTUM GX, you can model the overall geometry in 2D and seamlessly extrude it into 3D, adjusting as needed. That means you save a lot of time!
Extract 2D sections from complex 3D models
And it works the other way, too. If you’re working on a large 3D model with complex geometry, you may want to analyse specific sections in more detail, for example, to evaluate Factor of Safety.
With OPTUM GX, you can instantly extract 2D cross-sections and analyse them using standard plane strain methods.
This allows for fast and reliable sectional analysis — and it's an invaluable tool for quality assurance of complex 3D models.
Python Scripting
Tired of the repetitive grind of setting up geotechnical models with only minor parameter variations? We get it. Reconfiguring the same problem again and again wastes valuable time and breaks your workflow. That’s why we developed a smarter solution that transforms the way engineers handle model setup.
The OPTUM GX plugin for Python lets you automate your project setup — from geometry and materials to loads and boundary conditions — all directly from your script. No more repetitive manual input for every new iteration.
Need even more control?
GX supports custom scripting and automation, allowing advanced users to build tailored solutions, specialized workflows, or even full custom applications — all within the Optum environment.
Automate repetitive tasks: Quickly generate multiple project variants without rebuilding from scratch.
- Work faster, with fewer errors: Streamline your workflow and reduce the risk of manual setup mistakes.
- Accelerate iteration and optimization: Make quick modifications and rerun models with ease — perfect for parameter studies and design exploration.
“A past project required 3,000 hours to design 50 berms.
With Au2Rox™ 2.0 in auto mode, the same design was completed in just 3 hours — demonstrating a time-saving factor of 1,000 while using the custom plugin feature in OPTUM GX.”
