This program, based on the finite element method, can model and analyze a wide range of geotechnical problems, including terrain settlement, sheet pile/diaphragm walls, slope stability, excavation analysis. It offers several material models for soils and a variety of structural elements such as walls, anchors, geotextiles or geogrids. The GEO5 FEM is used to compute displacements, internal forces in structural elements, stresses and strains and plastic zones in the soil and other quantities in every construction stage. With extension modules the program also performs the Tunnel excavation analysis, the steady sate or transient Water Flow analysis, the coupled Consolidation analysis, or the dynamic impact of an Earthquake.

slope stability analysis

Variety of conventional and state-of-the-art material models:
- Linear elastic model
- Modified elastic model
- Mohr-Coulomb model
- Modified Mohr-Coulomb model with hardening/softening
- Drucker-Prager model
- Cam Clay model
- Hypoplastic model for clay
Wide range of common structural elements:
- Concrete walls, pile walls, soldier pile walls (Braced Sheeting) or reinforced tunnel lining are modeled
  by the beam elements with catalogued profiles and materials
- Anchors
- Nails
- Props
- Reinforcements (geotextiles, geogrids)
Contacts elements between soil and structure with nonlinear stress-displacement relation
The model consists of several construction stages to account for the construction process
Any number of surcharges (strip, trapezoidal, line load) can be added to the model in any construction stage
Boundary conditions are generated either automatically or defined specifically for chosen points or lines
The ground water table is either user-defined or computed in GEO5 FEM – Water Flow and imported via GeoClipboard
Each material model can be either in drained or undrained conditions
The stability analysis can be run in each construction stage with either static or earthquake loading providing a current factor of safety
An extensive list of variables (settlements, stresses, strains, plastic zones, pore pressure, etc.) is plotted
on either deformed or undeformed model
The distribution of internal forces and deformation of the structural elements is available
The evolution of quantities at chosen points is observed by the means of monitors and graphs
Automatic mesh generator issues warnings on problematic topology parts
The size of elements can be adjusted by point, line and free refinements
The program supports DXF import and export
