3D Geotechnical & Tunnel Analysis Software
A user-friendly 3D finite element software for subsurface geotechnical analysis—covering deformation, stability, groundwater, and tunnel modeling.
Key Workflows
Explore key features and workflows
3D Soil & Rock Modeling
Bring your projects to life with true 3D geological modeling. Create detailed models with layered soils, rock masses, and discontinuities, combined with smart mesh refinement for accuracy.
Tunnel & Excavation Design
Simulate mechanized (TBM) and NATM excavation in a fully 3D environment with staged construction and soil-structure interactions to minimize construction risks with phase-by-phase analysis.
Groundwater Flow & Consolidation
Perform steady-state and transient seepage, as well as time-dependent consolidation in 3D. This gives you actionable insights to protect your structures and ensure long-term stability under real-world conditions.
