Limit analysis provides an efficient means of assessing the bearing capacity of geostructures directly without the need for exhaustive load-displacement analysis.
Mesh Adaptivity
All analyses come with the option of using automatic adaptive mesh refinement. This allows for a high degree of accuracy at a moderate computational effort.
Strength Reduction
Strength reduction analysis involves a reduction of the material parameters until failure occurs. The resulting reduction factor may be interpreted as the factor of safety.
Initial Stress Analysis
Geostatic stresses are determined in an efficient and rigorous manner using this analysis which is unique to OptumG2.
Staged Construction
Staged construction comes with a high degree of flexibility and any changes to material, geometry, etc, between stages are specified in an ad hoc manner.
Elastoplastic Analysis
Elastoplastic analysis can be carried out in an efficient and robust manner using the dedicated algorithms implemented in OptumG2.
Design Approaches
OptumG2 includes user-friendly functionality for automatic application of partial factors according to the various Design Approaches of Eurocode 7.
Accurate Soil and Rock Models
OptumG2 comes with both simple and advanced constitutive models for soil and rock including Mohr-Coulomb, Hoek-Brown, Modified Cam Clay, and EMC.
