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 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.

PLAXIS 2D is a powerful and user-friendly finite-element (FE) software for 2D analysis of deformation and stability in geotechnical engineering and rock mechanics. PLAXIS is used worldwide by top engineering companies and institutions in the civil and geotechnical engineering industry.

PLAXIS 2D is ideal for a range of applications from excavations, embankments, and foundations to tunneling, mining, oil and gas, and reservoir geomechanics. PLAXIS 2D includes all the essentials to perform deformation and safety analysis for soil and rock that do not require the consideration of creep, steady state groundwater or thermal flow, consolidation analysis, or any time-dependent effects.

User-friendly, Finite Element Software: PLAXIS capabilities work together to build a powerful and intuitive finite element package for geotechnical analysis of soil, rock, and associated structures. Renowned for sound computation, PLAXIS offers a large range of material models to accurately model the behavior of various soils and rock types, which together provide realistic assessment of stresses and displacements.

Fast and Efficient, Finite Element Model Creation: PLAXIS guides users across several modes to efficiently create models with a logical geotechnical workflow. PLAXIS 2D models geometry via predefined structural element types and loading types using CAD-like drawing capabilities that lead to fast and efficient finite-element model creation. For tunnel solutions, a designer wizard builds off quick creation and can edit tunnel cross-sections, specify reinforcements, tunnel lining, and loading conditions. The Mesh mode features automatic and manual mesh refinements, automatic generation of irregular and regular meshes, and capabilities to inspect the mesh quality.

Drive efficiency with multidiscipline workflows: Create logical geotechnical digital workflows that take projects from subsurface imports through design and analysis to various outputs.
