  • PLAXIS 3D
  • What is PLAXIS 3D?

    PLAXIS 3D includes the most essential functionality to perform everyday deformation and safety analysis for soil and rock. This comprehensive software for the design and analysis of soils, rocks, and associated structures makes it easy to model in full 3D.

    Reliably solve infrastructure challenges

    Easily generate and scale construction sequences for excavations. Facilitate steady-state groundwater flow calculations, including flow-related material parameters, boundary conditions, drains, and wells. Use interfaces and embedded pile elements to model movement between soil and foundation, such as slipping and gapping. Get trustworthy results with realistic soil models and a complete portfolio of visualization abilities.

    Get realistic assessments of stresses and displacements

    To meet the unique geotechnical challenges of soil structure interactions, PLAXIS 3D offers different calculation types, such as Plastic, consolidation, and safety analysis. A range of material models for predicting the behavior of various soils and rock types, combined with robust calculations, helps ensure reliable results. You can display these forces in various ways and use cross-section applications to inspect certain areas in greater detail.

    Drive efficiency with multidiscipline workflows

    Create logical geotechnical digital workflows that take projects from subsurface imports through design and analysis to various outputs.

  • PLAXIS 3D Ultimate
  • What is PLAXIS 3D Ultimate?

    PLAXIS 3D Ultimate extends the capabilities of PLAXIS 3D Advanced so you can analyze the effects of vibrations in the soil, like earthquakes and moving traffic loads. You can also simulate complex hydrological conditions through time-dependent variations of water levels or flow functions on model boundaries, as well as soil boundaries. 

    3D Geotechnical Dynamic Modeling

    PLAXIS 3D Ultimate is an easy-to-use software that is suited for more advanced seismic analysis. When you need something that goes beyond the low-frequency vibrations, this is the choice for you. You can:

    • Analyze the effects of human-made or natural seismic vibrations in soil
    • Perform analyses on the effects of vibrations in the soil from earthquakes, pile driving, vehicle movement, heavy machinery, or train travel
    • Accurately calculate the effects of vibrations with a dynamics analysis when the frequency of the dynamic load is higher than the natural frequency of the medium
    • Perform a ground response analysis and liquefaction analysis using the UBCSand model

    3D Geotechnical Groundwater Flow

    Go beyond the default options of steady-state groundwater flow analysis of PLAXIS with PLAXIS 3D Ultimate.

    • Simulate the unsaturated, time-dependent, and anisotropic behavior of soil
    • Simultaneously calculate changes in pore pressures and deformation by performing a fully-coupled flow-deformation analysis
    • Use the Flow-only mode to exclude displacements and stresses from the calculation if you are only interested in groundwater flow, making it easier to use.

  • What is PLAXIS 3D WorkSuite?

    PLAXIS 3D WorkSuite includes everything that you get with PLAXIS 3D Ultimate, plus you get PLAXIS 3D LE, and PLAXIS Designer.

    PLAXIS 3D LE

    With PLAXIS 3D LE you can model and analyze geo-engineering projects for limit equilibrium slope stability analysis and perform finite element analysis of groundwater seepage in unsaturated or saturated soils.

    PLAXIS Designer

    PLAXIS Designer is excellent for building 3D conceptual models to overcome the challenges of merging and analyzing data. With Bentley’s open modeling environment, PLAXIS Designer allows you to visualize and manipulate geotechnical data including topology, boreholes, piezometers, and other field instrumentation data, as well as engineering staged construction and design.

User Quote

"The power to collaborate with design, construction, and the owner is where PLAXIS really shines. During meetings, I can quickly respond to stakeholder requests by adjusting geometry and sharing multiple scenarios. Being able to model “on the fly” helps us avoid wasting time going back and forth on emails and phone calls."

Frequently Asked Questions

PLAXIS is an easy-to-use, finite element software application that helps with the analysis of subsurface environments for geoengineering projects.

PLAXIS is a computer application that performs finite element analyses (FEA) within the realm of geotechnical engineering, including deformation, stability and water flow. The name PLAXIS comes from Plastic and AXISymmetry, indicating the geometric types handled in the original code of the software application.

Whilst lots of PLAXIS 3D tutorials can be found on Bentley Communities, here are some FREE PLAXIS 3D learning resources available in our eStore.

By applying interface elements PLAXIS users can simulate the interaction between a structure and soil. While without an interface no relative displacement (slipping/gapping) will be possible between structure and soil.

When interface applied, node pairs will be created at the interface of structure and soil. Each node pair consists of two nodes – one belongs to the structure and the other belongs to the soil. The interaction between these two nodes consists of two elastic-perfectly plastic springs. One elastic-perfectly plastic spring to model the gap displacement and one elastic-perfectly plastic spring to model slip displacement.

If you want to receive tailored training or attend a PLAXIS 3D course that is specific to your project requirement, Bentley offers extra training and mentoring services. You can choose from tailor-made training, on-demand learning, consulting services, mentoring and more. Learn more about Expert Services here.
