We are proud to announce the release of DeepEX 2026, the latest version of our industry-leading deep excavation and shoring design software. Available starting January 2026, this release represents a major step forward in computational power, modelling realism, and workflow efficiency.
DeepEX 2026 introduces advanced nonlinear analysis capabilities, expanded 3D FEM functionality, enhanced soil and structural modelling, and new design wizards aligned with international standards. With significant solver optimizations and new automation tools, engineers can now tackle larger, more complex projects with greater confidence, accuracy, and speed.
Key Enhancements and New Capabilities
Advanced Structural & Material Modelling
Nonlinear Fiber Section Analysis
Structural elements now support nonlinear fiber section analysis, enabling accurate modelling of complex sectional behavior and advanced material nonlinearity.
Enhanced Pile Modelling in 3D FEM
Support for multiple-section piles allows engineers to model realistic pile geometries with varying properties along depth.
Optimization of Wall Reinforcement
Automated optimization for walls with multiple reinforcement zones, accommodating reinforcement changes with depth.
Next-Generation Soil Constitutive Modelling
Advanced Small-Strain Soil Hardening Model
Implementation of a smooth small-strain constitutive law based on Bower et al. (2018), delivering significantly faster convergence compared to earlier small-strain models (Benz et al.).
Unsaturated Soil Response (LEM)
Enables more realistic modeling of partially saturated ground conditions.
Anisotropic Soil Strength Profiles (LEM)
Supports directional soil strength behavior for more accurate stability analyses.
Liquefaction Soil Model (Coming Early 2026)
A Dafalias-based liquefaction model is currently under development and will be released shortly after DeepEX 2026.
Expanded 3D FEM Capabilities
3D FEM Tunneling Wizard (TBM & SEM)
A new intuitive wizard simplifies 3D tunnel geometry, loading, and staging definition.
Tree-view tunnel staging interface
Seamless 2D-to-3D model conversion for TBM and SEM tunneling projects
3D FEM Consolidation Analysis
Fully coupled fluid–soil–structure interaction under time-dependent loading is now available in 3D FEM, allowing more realistic prediction of settlement and pore pressure dissipation.
Solver Optimization for Large-Scale Models
Major re-architecture of memory management enables efficient analysis of very large 3D FEM models exceeding 1 million DOFs, significantly improving performance and stability.
User Customization & Automation
User-Defined Constitutive Models via Python
Engineers can now create and integrate custom constitutive models using a flexible and accessible Python scripting interface, opening the door to project-specific material behavior.
New Design Wizards & Coastal Engineering Tools
Seawall, Embankment, and Revetment Wizards
Developed following Rock Manual guidelines, these wizards streamline coastal structure modeling and stability evaluation, including:
Surface roughness
Impact wave forces
Wave transmission and reflection
Flow-through rate estimation
Stability numbers
Crown wall and armor stability
Improved Geometry & Section Generation Tools
Draw 2D design sections without a wall, automatically tracing ground elevations and generating soil and water profiles.
Automatically generate multiple 2D sections along a polyline, with options for:
Sections normal to alignment
Automatic detection of steepest direction (Available under the 3D Model Wizard)
New 2D Wizard Option: Ability to retain the existing ground surface (currently for one wall at a time).
Limit Equilibrium Method (LEM) Enhancements
Inclined rakers connecting wall-to-wall for LEM analysis (2D FEM option planned for early 2026)
Transient water flow analysis
Unsaturated soil response
Anisotropic soil strength profiles
Codes & Standards
New Design Code Added: Austrian Eurocode 7
