ZSOIL.PC : A Windows-Based Tool offering a unified approach to numerical simulation of soil and rock mechanics, underground structures, excavations,
soil-structure interaction and underground flow, including dynamics, thermal and moisture migration analysis.
ZSOIL.PC is a continuously upgraded geotechnical, foundation and underground flow engineering software based on the finite-element method and written
in the MS-Windows environment. The program has been used with great success in forensic analysis and design studies, covering without exception all possible
scenarios encountered in real world case studies. ZSOIL.PC is the first integrated computer code that offered a unified approach to most of the natural processes
encountered in geotechnical and foundation engineering, including stability, consolidation, creep and underground flow, excavations and soil-structure interactions.
ZSOIL.PC has been developed at Zace Services Ltd since 1982. The latest versions of ZSOIL.PC were developed by a team led by A.Truty, K.Podles & Th.Zimmermann,
with research experience at the Swiss Federal Institute of Technology, Cracow University of Technology, U.C.Berkeley, and Caltech.
Examples of ZSOIL.PC Applications - Typical engineering problems that are being handled worldwide with ZSOIL.PC, in foundation and earthwork construction,
include tunnels, underground storage facilities, metro stations, mining, cut or fill in highways, railroads, dams, temporary and final retaining structures, water-front
and excavation systems with complex excavation sequences, hydraulic structures, and buildings.
Express-Worldwide-Consulting Services -Zace Services Ltd and selected partners offer worldwide development and meta-consulting services
( full data preparation and analysis of your problem except post- processing and reporting which you want to personalize).
Partners also offer worldwide consulting services and
assistance in all aspects of geotechnical and civil
engineering.

MAIN FEATURES OF ZSOIL.PC
- The program offers the following features:
ZSOIL MENU
Implemented in a menu-driven Integrated Computer Environment using the latest MS-Windows platforms (NT, 2000, XP,VISTA, Windows 7) :
the management of data files and executables is handled by the user in a very easy and natural way through dialog boxes and menu options.
Basic / advanced user configurations are available. Import of data from Autocad and from or to Excel is possible.
ZSOIL ANALYSES
Automatic memory release to optimize computer use, Data checking capabilities.
Nonlinear small and large displacements. Axi-symmetric, Plane strain, and 3D drivers offering single and 2-phase analyses,
with any combination of the following algorithmic options:
- Automatic evaluation of initial stress conditions including steady state flow: combination of gravity and initial-stresses allows an automatic
reproduction of the most complex initial state conditions, including existing constructions.
- Stability analysis: through C-phi reduction and stress level algorithms lead to a reliable assessment of safety factors and failure surfaces for
the most general problem geometries. Simpler and more general than usual sliding surface approaches.
Possibility to analyze safety with respect to local material properties or features like contact surfaces.
- Ultimate load analysis and deformation analysis.
- Prestress conditions (anchors).
- Simulation of Excavation, construction stages, simulation of fill for cut and cover construction, combined with any sequence of drivers,
allowing removal or addition of construction parts, loads, boundary conditions etc, unloading control capability in order to simulate
3-dimensional effects in 2D. Continuous safety assessment.
- Consolidation, volumetric and deviatoric creep and swelling (time dependent processes).
- Flow, steady or transient, fully or partially saturated, with time dependent boundary conditions; fullly arbitrary flow conditions with free surface,
seepage surfaces, as well as rain inflow, impermeable zones, coupled or uncoupled with solid deformation can easily be accounted for.
- Thermal/or moisture migration analysis: Transient thermal/or moisture migration analysis can be performed as a preprocessing in order to define
temperature time-histories to be accounted for later in the mechanical analysis.
- Dynamic time integration and Pushover analysis for structures
Skyline, or new sparse solvers, tested up to over 1'000 000 DOFs for symmetric stiffness matrices and 600 000 .DOFs for nonsymmetric ones

Units management : although any set of coherent units can be used, the program offers a convenient units management capability for increased comfort.
SOIL IDEALIZATION
Constitutive Models - ZSOIL.PC uses the most robust numerical algorithms to simulate nonlinear, time dependent, soil behavior, according to the Tresca,
Mohr-Coulomb w. dilatancy cut-off, Rankine, Drucker-Prager-Cap, and Cam-clay, Hardening small strain models for soil, multi-laminate for layered media and schists,
Hoek-Brown models for rock, Menιtrey-Willam (with softening) for concrete and Biot models for the consolidation and two-phase problems,
monotonic ECP-Hujeux model for complex soil behaviours; user defined models capability for continuum, user defined fiber model for beams.
The program can efficiently simulate any types of load and soil stress conditions, for example: Gravity fields and initial stress conditions
Water table and water pressures under steady state or transient conditions, including time dependent boundary conditions
Drained and undrained soil conditions Explicit definition of excavation/construction sequences Imposed displacement fields
Concentrated and distributed loads applied at the boundaries of the soil medium Unloading control for convergence analysis in tunnels infinite or semi-infinite media.
User models- Users can introduce their own constitutive model.
Element library - The nonlinear finite element scheme incorporated in Z_SOIL.PC uses 2D, 3D and axi-symmetric elements which optimally represent the nonlinear
constitutive soil models and overcome locking phenomena often associated with incompressible and dilatant behaviour.
Structural elements complete the element library, including linear and nonlinear beams, with hinges, flexibility based nonlinear beams (allowing 1 element /beam),
shells (including reinforced concrete), with possible hinges, membrane, geotextile, reinforcement and cable behaviours. Finally, infinite media and
a new frictional contact mortar and node to segment interface elements (permeable or impermeable ) are available for single or two-phase media.
These elements offer the flexibility to model any configuration of the soil profile.
Documentation and support - Practicing geotechnical engineers with little formal experience in numerical modeling or plasticity theory can learn how to use ZSOIL.PC
in a very short time using the "user-friendly" automated environment of the program a Getting started manual for beginners
and a In addition, the user will find:
A user interface with basic/advanced entry level A fully interactive online help and manual with indexed access A User's Manual which includes information on
program execution, data entry screens and extensive documentation of the analysis options. In-depth tutorials on how to use the program and
A theoretical section which contains unique details on the algorithms An extensive list of benchmark problems. A selection of representative case studies.

ZSOIL.PC Story
ZSOIL v1 came out in 1985 after three years of development and testing. It was backed by over 30 years of experience in
the field of numerical analysis, finite elements and soil plasticity. ZSOIL.PC v1 was developed at Zace Services Ltd under the supervision of
Th.Zimmermann, B. Dendrou & C. Rodriguez, with research experience at the Swiss Federal Institute of Technology, U.C. Berkeley, Caltech,
and Purdue University. Over 50 people have since then contributed to the development of successive versions, and several are still part of the team.
Since the early nineties, a ten-years close collaboration with the Swiss Federal Institute of Technology in Lausanne, and several major swiss engineering companies
has been successfully developed. Over the years long or short-term collaborations have also been initiated worldwide with researchers in numerical geomechanics.
ZSOIL has now over three thousand installations and a worldwide distribution, it is in daily use in a number of engineering offices to solve simplest and most complex
geotechnical and structural problems, and in many universities as teaching tool. Several custom versions of the program have been developed upon requests
from customers and recent versions include new constitutive models, multiphase dynamics for the simulation of liquefaction.
