PLAXIS 2D - 2D geotechnical engineering software

Solve Geotechnical Challenges

Every project is challenging, but the geotechnical analysis doesn’t have to be. PLAXIS 2D provides the power of fast computations. Perform advanced finite element or limit equilibrium analysis of soil and rock deformation and stability, as well as soil structure interaction, groundwater, and heat flow.

Model and analyze geo-engineering projects with finite element analysis in 2D

PLAXIS 2D is a user-friendly, finite-element package that provides you with the ability to model diverse geotechnical problems from a single, integrated application. You can analyze the deformation and stability of projects ranging from excavations, embankments, and foundations to tunneling, mining, and geomechanics.

We offer various versions of PLAXIS 2D, so you can choose which one is best for you:

PLAXIS 2D

PLAXIS 2D includes all the essential functionalities to perform everyday 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.

PLAXIS 2D Advanced

PLAXIS 2D Advanced includes everything that is included in PLAXIS 2D, plus it offers more advanced features and material models to consider creep, flow-deformation coupling through consolidation analysis and steady state groundwater or heat flow. It also solves your problems faster with the multicore solver.

Model diverse geotechnical problems
Create FE models quickly and efficiently
Simulate various types of soil and rock behavior
Achieve consistently accurate results
Conduct powerful and versatile post processing

PLAXIS 2D Ultimate

Extend the capabilities of PLAXIS 2D Advanced with additional capabilities for analyzing the effects of vibrations in the soil, such as earthquake and traffic loads; simulate complex hydrological, time-dependent variations of water levels, or flow functions on model or soil boundaries; and assess the effect of transient heat flow on the hydraulic and mechanical behavior of soil.

Dynamic Modeling
Groundwater Flow Analysis
Thermal Modeling

PLAXIS 2D WorkSuite

PLAXIS 2D WorkSuite is the most comprehensive option of PLAXIS 2D which includes PLAXIS 2D Ultimate and PLAXIS 2D LE. PLAXIS 2D WorkSuite integrates the powerful and user-friendly finite element and limit equilibrium analysis capabilities of PLAXIS applications for the design and analysis of soil, rock, and associated structures.
