What is PLAXIS 3D/PLAXIS 3D WorkSuite?

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. Tackle modeling challenges for even the most complex projects with advanced features.

Because every firm has different needs, there are two flexible PLAXIS 3D variations: PLAXIS 3D Basic and PLAXIS 3D WorkSuite.

PLAXIS 3D WorkSuite includes the following modules:

PLAXIS 3D Dynamics for dynamic loading modeling
PLAXIS 3D PlaxFlow for time dependent groundwater analysis

Reliably solve infrastructure challenges
Easily generate and scale construction sequences for excavations of any complexity. 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.

Create FE models quickly and efficiently
This comprehensive solution for the design and analysis of soils, rocks, and associated structures makes it easy to model in full 3D. Drawing tools, such as extrude, intersect, combine, and array operations facilitate finite element modeling, while multicore calculations and a 64-bit kernel can handle simple and complex models. Create safer infrastructures with fully-optimized designs.

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. 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.

Add to the application’s versatility
Extend the capabilities of PLAXIS 3D software with add-on modules. PlaxFlow makes analyzing complex groundwater flow easy, while Dynamics provides comprehensive and reliable dynamic load modeling.

MODULES INCLUDED IN PLAXIS 3D WORKSUITE

PLAXIS 3D Dynamics: 3D Geotechnical Dynamic Modeling Software

Analyze the effects of man-made or natural seismic vibrations in soil with PLAXIS 3D Dynamics. Perform analyses on the effects of vibrations in the soil from earthquakes, pile driving, vehicle movement, heavy machinery, or train travel. PLAXIS 3D Dynamics is an easy-to-use, add-on module to PLAXIS 3D; so, when you need something that goes beyond the low-frequency vibrations, this is the choice for you. PLAXIS 3D Dynamics module can handle more advanced seismic analysis than what is available by default in PLAXIS and can 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.

PLAXIS 3D PlaxFlow: 3D Geotechnical Groundwater Flow Software

Go beyond the default options of steady-state groundwater flow analysis of PLAXIS with the PLAXIS 3D PlaxFlow add-on module. Simulate the unsaturated, time-dependent, and anisotropic behavior of soil with PLAXIS 3D PlaxFlow. Simultaneously calculate changes in pore pressures and deformation by performing a fully-coupled flow-deformation analysis. Plus, the Flow-only mode excludes displacements and stresses from the calculation if you are only interested in groundwater flow, making this application easier to use.
