GEO2.0 | Specifications

This page provides a technical specification of LimitState:GEO, including details of key features of the software and also system requirements.

Wizards for quick generation of standard problem types.
Intuitive GUI allows user defined problems to be rapidly constructed.
Import geometries from CAD (dxf).
Quick and simple modifications to geometry, boundary conditions, materials and loading.
Multiple scenarios are handled with ease, and the critical case is always found. No need to separately analyse different potential failure modes.
Handle uncertain ground conditions by modelling multiple soil types in a single soil body (LimitState:GEO will always pick the critical case).
Directly apply Partial Factors in the analysis making it straightforward to use with design codes as such as Eurocode 7.
LimitState:GEO ships with a library of predefined partial factor sets for common design codes/approaches; however, the user can define (and save) an unlimited number of their own partial factor sets.
Groundwater table (horizontal or variably inclined) easily specified.

Standard material models include cohesive and frictional soils (Mohr-Coulomb). Rigid materials and materials with tension and compression cutoff can also be modelled.
Soil-structure interfaces easily defined and modelled.
Soil reinforcement models allow a range of reinforcement types to be represented.
Switch between drained and undrained analysis with a single mouse click.
LimitState:GEO ships with a library of pre-defined materials; however, the user can define (and save) an unlimited number of their own materials.

Built-in Eurocode 7 partial factor sets.
Simple switching between undrained and drained analyses.
Specify favourable or unfavourable loading and be alerted following analysis if this is incorrect for the critical mechanism.
Use the inbuilt 'Scenario manager' to define and solve multiple scenarios in one go (e.g. EC7 Design Combinations 1 & 2, drained and undrained cases etc.).

Solutions are based on rigorous and proven limit analysis methods.
Failure mechanisms are represented as slip-lines (a very familiar concept to geotechnical engineers).
If required, geo can generate simplified solutions that are amenable to hand checking.
Animated displacements provide a highly useful visual interpretation of the failure mechanism.
Analysis report output easily tuned to user preferences.
