LimitState:GEO 4.0

A redesigned interface, a much faster multithreaded solver and full support for second-generation Eurocode 7.

GEO 4.0 is the biggest update in LimitState:GEO’s history. It keeps the Discontinuity Layout Optimization (DLO) technology engineers rely on to find the critical failure mechanism, and rebuilds everything around it to make modelling, solving and checking faster and clearer.

What's NEW

Release Notes

Ready for second-generation Eurocode 7

Switch between Gen 2 factor sets, Gen 1 Design Approaches, a global factor of safety or your own sets, and re-solve to compare.

A modern, redesigned interface

A clean new look with less visual clutter, simpler navigation and hundreds of usability improvements, from resizable wizards to a first-time setup for units and factoring.

Significantly faster solving

Multithreading and enhanced solve algorithms cut solution times. New higher nodal density presets let you put that speed to work on more refined solutions.

Design to the new Eurocode 7 with confidence

Partial factor handling has been rebuilt from the ground up. Whether you are moving to EN 1997:2024, still working to the first generation, or designing outside the Eurocodes altogether, GEO 4.0 supports the factoring regime you need.

Choose your factoring regime: Gen 2 factor sets, Gen 1 Design Approaches, global factor of safety or user-defined sets
Consequence Classes: CC1, CC2 and CC3 adjustments applied automatically
Output Factoring (OFA) structural checks: factored action effects compared against resistances for engineered elements and joints, with a dedicated results summary and report section
Automatic favourable/unfavourable classification: helps ensure the right partial factors are applied to every action

More realistic modelling

GEO 4 More Realistic Modelling

Anisotropic soil strength

Model direction-dependent strength with Elliptic Square Function, NGI-ADP or user-defined models.

Flexible boundary loading

Specify loads as horizontal/vertical or shear/normal components, and use trapezoidal loads for non-uniform distributions

Easier pullout checks

Working overburden stresses, pullout strengths and interface stresses are shown directly for soil nails and strip reinforcement.

Finer Factor on Strength control

Choose which strength parameters are fully, partially or not factored, including Mp and limiting stresses.

Command-Line Interface included

Automate and batch your analyses, now as standard with every full licence.

Spatially Varying Strength included

Model strength fields that vary across the problem, now as standard with every full licence.
