ZSOIL ANALYSES
Nonlinear FE analyses offering single and 2-phase analyses:
- Plane strain
- Axisymmetric
- 3D


Constitutive models for continuum include:
- Elastic
- Elastic for structures (Continuum for Structures)
- Mohr-Coulomb
- Hardening Soil including small strain formulation (HS-Brick)
- Hoek-Brown, original and advanced formulations including hardening and softening mechanisms
- Multi-laminate for modeling foliated rocks
- Drucker-Prager
- Modified Cam-Clay
- Cap model
- Densification model for liquefaction
- Menétrey-Willam for simplified concrete behavior
- Damage-Plastic Concrete model (with fire extension)
- Interface 

Stability analysis. through tan(phi)-c reduction and stress level algorithms 
Simulation of excavation and construction stages, 
Consolidation, volumetric and deviatoric creep and swelling (time dependent processes).
Flow, steady or transient, fully or partially saturated, with time dependent boundary conditions; 
    fully arbitrary flow conditions with free surface, seepage surfaces, 
    as well as rain inflow, impermeable zones, coupled or uncoupled with solid deformation 
Thermal/or moisture migration analysis: Transient thermal/or moisture migration analysis 
Dynamic time integration and Pushover analysis for structures, including soil structure interaction.

Structural elements
- Truss (elastic or elasto-plastic)
- Anchor (elastic or elasto-plastic anchorage section)
- Beam (elastic) or composite beams (core material + reinforcement)
- Nail (embedded beam with ultimate shear strength resistance)
- Pile (embedded beam with Coulomb frictional interface)
- Tendon (pretensioned or posttensioned cables)
- Membrane (elastic or elasto-plastic)
- Thin shell (elastic or non-linear composite)
- Thick shell (elastic or non-linear composite)
- Beam hinge
- Shell hinge

Prestress conditions (typically used for anchors, struts, tendons)
Imposed stress or strain conditions (e.g. design accounting for thermal dilation for struts)

Sparse solvers, up to 1’500 000 DOFs for symmetric stiffness matrix 
and 1’000 000 DOFs for non-symmetric ones.

Data preparation
- CAD assistance: import of geometries from DXF and Rhino formats
- Flexible and unconstrained workflow during model preparation
- Creating geological model based on boreholes and kriging interpolation
- Data import from existing models (materials, boreholes, geometry and many others)
- Possibility of assembling of a final model from subsidiary models (team-oriented workflow)

Analysis of results
- Post-processor enables a full inspection of computed variables in the form of color maps,
  diagrams, time-histories
- Envelope diagrams
- Data export to CSV files
- Python SDK for customizing data analysis and reporting
- Export of results to Paraview for alternative viewing
