Why OPTUM GX for Soil Modelling?
Soil modelling software allows engineers to simulate and understand how soil behaves under load, drainage, and deformation. From slope stability and seepage to foundation performance and soil–structure interaction, accurate modelling is key to designing safe, economical, and sustainable ground structures.
OPTUM GX is a fully FEM-based geotechnical software for advanced soil and structure analysis in both 2D and 3D. Built on the Finite Element Method (FEM) and Finite Element Limit Analysis (FELA), it delivers fast, stable, and realistic results — without assumptions about how failure occurs.
Why OPTUM GX for Soil Modelling?
OPTUM GX combines realism, precision, and efficiency in one geotechnical platform:
Finite Element Soil Modelling: Simulate stress, strain, and pore pressure behaviour under complex load and boundary conditions.- Coupled Seepage and Deformation: Model how hydraulic and mechanical behaviour interact over time — under both steady-state and transient conditions.
- Advanced Stability Assessment: Perform soil slope stability analysis using Strength Reduction and FELA methods for verifiable safety factors.
Built entirely on FEM and FELA, OPTUM GX replaces assumptions with accuracy — helping engineers save time, reduce uncertainty, and optimise design with confidence.
Numerical Soil Analysis for Ultimate and Serviceability Design States
OPTUM GX enables engineers to evaluate both Ultimate Limit States (ULS) and Serviceability Limit States (SLS) within a consistent FEM–FELA framework. FELA determines true collapse loads based on plasticity theory, while FEM-based Strength Reduction provides insight into deformation and serviceability. This dual approach ensures safe, efficient designs with minimal iteration and a full understanding of soil–structure performance.

Key Features in OPTUM GX
Numerical Soil Behaviour Analysis
OPTUM GX captures soil response under realistic loading — from settlements and stress redistribution to failure mechanisms.
Users can define advanced constitutive models, apply staged construction, and set complex boundary conditions to replicate field behaviour with precision.
Seepage and Pore Pressure Modelling
Analyse groundwater flow and pore pressure changes under steady or transient conditions.
Results such as the phreatic line, seepage quantity, and saturation zones can be directly linked to stability analyses — providing deeper insight into how hydraulic effects influence soil safety.

Seepage analysis software
Finite Element Limit Analysis (FELA)
Determine true failure loads without predefined failure surfaces.
Using upper, lower, and mixed elements, OPTUM GX brackets collapse loads within tight bounds — delivering transparent, verifiable measures of stability.

OPTUM GX vs Other Soil Modelling Tools
Unlike traditional programs that mix LEM and FEM or separate 2D and 3D into different products, OPTUM GX provides a unified FEM-only environment. It eliminates mesh convergence issues, avoids numerical troubleshooting, and automates documentation — saving time while improving reliability.
With full Python scripting for automation, batch runs, and report generation, OPTUM GX streamlines workflows and makes numerical soil analysis faster and more consistent than ever.
