PLAXIS is the leading geotechnical finite element software, specifically developed for the 2D and 3D analysis of deformation, stability and groundwater flow.It is currently used by over 3000 engineers worldwide in the civil engineering, nuclear, oil & gas and renewable energy industries. Renowned for its ease of use and accurate soil models, it will help you optimise your designs and reduce conservatism compared to relying on traditional methods.

Extend your capabilities with PLAXIS 2D 2017 ... Cross and parallel permeability in interfaces: In the Interfaces tab of the material dataset users can now select between permeable, impermeable and semi-permeable options to define the cross permeability.  Parallel permeability is defined here as well. Output facilities have been extended with options to inspect the flow through and along the interfaces. Non-linear geogrids: Elastoplastic (N-ε) & Viscoelastic (time-dependent): PLAXIS 2D 2017 introduce two new types of behavior for geogrids. Users can now include elastoplastic, or viscoelastic behavior. For the elastoplastic behavior user can define N-epsilon diagrams. With the viscoelastic behavior, creep can be taken into account for geogrids. Multiply command for numeric properties (VIP): The multiply command can be used to for instance multiply a set of loads with various load components by a factor higher or lower than 1. This command can be issued in the various modes on numerous objects, and especially for staged construction offers a convenient way to explore alternate load conditions, thermal conditions, initial conditions etc. Command line improvements: 2D 2017 brings some improvements for the command line window. Users can now right click in the command line window and choose the Pop-out option to detach the command line window from the program. In addition some extra options to copy all successful commands or responses are available.

PLAXIS 2D is a finite element package intended for the two dimensional analysis of deformation and stability in geotechnical engineering. It is equipped with features to deal with various aspects of geotechnical structures and construction processes using robust and theoretically sound computational procedures.

With PLAXIS 2D the geometry of the model can be easily defined in the soil and structures modes, after which independent solid models can automatically be intersected and meshed. The staged construction mode allows for simulation of construction and excavation processes by activating and deactivating soil clusters and structural objects. The calculation kernel enables a realistic simulation of the non linear, time dependent and anisotropic behaviour of soils and/or rock. Since soil is a multi phase material, special procedures allow for calculations dealing with hydrostatic and non hydrostatic pore pressures in the soil. The output consists of a full suite of visualization tools to check the details of the 2D underground soil-structure model. Typical PLAXIS applications include: assessing street level displacements during the tunnel construction, consolidation analysis of embankments, soil displacements around an excavation pit, dam stability during different water levels, and much more.

Plaxis 3D Foundation v1.6.0.193 [Size: 138 MB] ... PLAXIS 3D is a finite element package intended for three-dimensional analysis of deformation and stability in geotechnical engineering. It is equipped with features to deal with various aspects of complex geotechnical structures and construction processes using robust and theoretically sound computational procedures. With PLAXIS 3D, complex geometry of soil and structures can be defined in two different modes. These modes are specifically defined for Soil or Structural modelling. Independent solid models can automatically be intersected and meshed.

The staged constructions mode enables a realistic simulation of construction and excavation processes by activating and deactivating soil volume clusters and structural objects, application of loads, changing of water tables, etc. The output consists of a full suite of visualization tools to check details of the complex inner structure of a full 3D underground soil-structure model. PLAXIS 3D is a user friendly 3d geotechnical program offering flexible and interoperable geometry, realistic simulation of construction stages, a robust and reliable calculation kernel, and comprehensive and detailed post-processing, making it a complete solution for your daily geotechnical design and analysis.

2D PlaxFlow is an add-on module to the PLAXIS 2D program. Geotechnical applications require advanced numerical tools and constitutive models for the simulation of the non-linear, time dependent and anisotropic behaviour of soils and/or rock in saturated and partially saturated situations. For many practical applications it is necessary to take into account both deformation and groundwater flow. For time dependent analysis, this leads to mixed equations of displacement and pore pressures, called coupled hydro-mechanical approach, which have to be solved simultaneously. This type of analysis which is based on Biot’s theory of consolidation enables the user to simultaneously calculate deformation and groundwater flow with time-dependent boundary conditions in saturated and partially saturated soils.

Modelling: Time dependent groundwater boundary conditions (linear, harmonic and user defined) + Various boundary conditions for flow (seepage, head, prescribed boundary flux, infiltration/precipitation, drains and wells) + Various Soil Water Characteristic Curves (SWCC) (Mualem-Van Genuchten, approximate Van Genuchten and user defined) + Various predefined data sets for  SWCC based on different soil classification systems (standard, Hypres, USDA and Staring) + Bishop stress and suction as state variables for unsaturated soil models + User defined soils model for unsaturated soils + Transient external water loads on closed boundaries are automatically calculated. Calculations: Possibility to perform fully coupled flow-deformation analysis + Automatic time stepping for fully coupled flow-deformation and groundwater flow analyses + Possibility to simulate mechanical behaviour of partially saturated soils in all existing types of calculations (plastic, safety, dynamics and consolidation analyses) + Option for Flow Only calculation. Results: Flow results in addition to displacements and stresses + Darcy’s velocities + Suction + Degree of saturation + Relative permeability + Groundwater head. Applications: Simulations of unsaturated soil behaviour + Earth and rockfill dams (time dependent problems) + Staged construction in time + Analysis of rapid drawdown situations + Slope stability analysis (landslides, effect of environment (rain, flooding etc.) on slope stability) + Soils with collapse risks (compacted soils) + Drainage systems.

The 2D Dynamics module is an extension to PLAXIS 2D. Geotechnical applications require advanced constitutive models for the simulation of the non linear, time dependent and anisotropic behaviour of soils and/or rock. Although the modelling of the soil itself is an important issue, many projects involve the modelling of structures and the interaction between the structures and the soil. 2D Dynamics offers the tools to analyse the propagation of waves through the soil and their influence on structures. This allows for the analysis of seismic loading as well as vibrations due to construction activities. 2D Dynamics offers the possibility to perform dynamic calculations in individual calculation phases.

Product features: New and improved Dynamics features in PLAXIS 2D 2015: Consistent mass matrix and mass matrix parameter for improved dynamic calculation results + Dynamic multiplier for bending moment component of point load. Modelling: Time-dependent dynamic load systems for point loads, distributed loads and prescribed displacements (velocities, acceleration) + Different dynamic loading types: harmonic, table, SMC structured data + Independent application of horizontal and vertical displacement (velocity, acceleration) components + Absorbent (viscous) boundaries to absorb waves at the model boundaries + Free Field & Compliant Base Boundaries (VIP) + Tied degrees of Freedom as dynamic boundary condition (VIP) + Rayleigh damping (aR and ßR) per material data set for soil layers and structures + Smooth meshes, to prevent numerical oscillations and internal reflections + HSsmall model including small-strain stiffness, modulus reduction and hysteretic damping + Upon request: UBCSAND liquefaction model (available as User-Defined Soil Model) (VIP). Calculations: Automatic time stepping using dynamic sub-steps + Selection of Newmark time integration scheme (aN and ßN) + Calculation type Dyamics available + Baseline correction for accelerogram. Results: Velocities and acceleration in addition to displacements + Envelopes of structural forces and displacements + Time-displacement, Time-velocity, Time-acceleration curves + Liquefaction analysis + Switch from time-curves to frequency-curves using Fast Fourier Transform + Pseudo Spectral Acceleration response spectrum. Applications: Single source vibrations + Earthquake simulation + Dynamic soil-structure interaction + Evaluation of natural frequencies and resonance + Embankment stability under dynamic loading + Machine and traffic vibrations + Impact loading + Structural response under earthquake loading + Racking of tunnel lining.
