Model and analyze geo-engineering projects with finite element analysis in 3D

PLAXIS is a user-friendly, finite element package with trusted computation that is used by geotechnical engineers globally. PLAXIS 3D offers CAD-like drawing capabilities to help with the analysis of subsurface environments for geoengineering projects. From excavations, embankments, foundations, tunneling, and mining, to reservoir geomechanics, users can determine the deformation and stability of geotechnical engineering and rock mechanics to assess the geotechnical risk.

Because every firm has different needs, there are multiple variations of PLAXIS 3D.


PLAXIS 3D includes the most essential functionality to perform everyday deformation and safety analysis for soil and rock, which do not require the consideration of creep, steady state groundwater, consolidation analysis, or any time-dependent effects.

PLAXIS 3D Advanced

PLAXIS 3D Advanced includes everything that is included in PLAXIS 3D, plus enhances your geotechnical design capabilities with more advanced features and material models to consider creep or flow-deformation coupling through consolidation analysis. It also solves your problems faster than PLAXIS 3D with the multicore solver.

PLAXIS 3D Ultimate

Extend the capabilities of PLAXIS 3D Advanced to deal with the most challenging geotechnical projects. With PLAXIS 3D Ultimate 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 flow functions on model boundaries, as well as soil boundaries.

PLAXIS 3D WorkSuite

PLAXIS 3D WorkSuite includes PLAXIS 3D Ultimate, PLAXIS 3D LE, and PLAXIS Designer.

What is PLAXIS 3D?

As infrastructure assets are crucially linked to subsurface environments, they are vulnerable to geotechnical risk. Perform three-dimensional finite element analysis of deformation and stability in geotechnical engineering and rock mechanics with PLAXIS 3D. A comprehensive solution for design and analysis of soils, rocks, and associated structures, PLAXIS 3D allows you to make safe, cost-efficient decisions that offer fast, and reliable comprehensive analysis methods. The PLAXIS interface guides you across several modes to efficiently create models with intuitive digital geotechnical workflows. Used on projects of all types, ranging from excavations, embankment and foundations to tunneling, mining, and reservoir geomechanics, the software is equipped with advanced features to tackle modeling challenges in both common and complex geotechnical projects. – Fast and efficient finite element model creation – Enhanced applications with trusted computation – Staged-construction modeling and analysis capability – Suite includes Dynamics for load modeling and PlaxFlow for groundwater analysis Bentley’s geotechnical applications are backed by world-class expertise and used worldwide to support producing safer structures and environments for all. Strengthen your solutions with the digital workflows and trusted computation of PLAXIS.
