2D/3D Limit Equilibrium Software

The Essential for LEM Slope Stability Analysis

Accomplish engineering analysis of slope stability, groundwater flow, and consolidation.

What is PLAXIS LE?

With PLAXIS 2D LE or PLAXIS 3D LE you can model and analyze geoengineering projects with limit equilibrium. These powerful software applications for limit equilibrium slope stability analysis and finite element analysis of groundwater seepage provide rapid, comprehensive analysis for various conditions.


  • Create Conceptual Designs
    Build 3D conceptual models in PLAXIS Designer for geotechnical analysis applications like slope stability, groundwater, consolidation, and stress/deformation.

  • Meet Project Requirements and Design Scenarios
    Design to standards like Eurocode 7 or BS 8006. Incorporate reinforcements, dynamic loads, unsaturated conditions, climatic effects, and anisotropic bedding.


  • Analyze Slope Stability
    Create 2D and 3D limit equilibrium slope stability models of soil and rock slopes. Take advantage of the comprehensive set of search methods and more than 15 analysis methods. Use multiplane analysis (MPA), for enhanced spatial slope stability analysis.

  • Integrate Groundwater and Consolidation Analysis
    Perform analysis on embankments, dams, reservoirs, and cover systems through earth structures and broader hydrogeological settings.

  • Automate Workflows
    Save time with automatic sliding direction determination, efficient search, probability analysis, and sensitivity analysis.

Choose from PLAXIS 2D LE or PLAXIS 3D LE.

PLAXIS 3D LE includes everything in PLAXIS 2D LE, plus:

  • 3D analysis
  • Complex geometry creation
  • Parallel processing to save time

*Prices vary per region. For more options, see licensing and subscriptions section.

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."

One-time purchase with support

Perpetual License with SELECT

A perpetual license of Bentley software is a one-time purchase, with a yearly maintenance subscription, called SELECT. This includes 24/7/365 technical support, learning resources, and the ability to exchange licenses for other software once a year. With SELECT, you will benefit from:

  • License pooling, so you can access your software from multiple computers.
  • Access additional Bentley software with Term Licenses, which allow you to pay for what you use without the upfront cost of purchasing a perpetual license.

Annual renewal quotes are delivered directly to your inbox, and our experienced Renewal Representatives are available to answer your questions and guide you through any changes you’d like to make.
