    What is PLAXIS 2D?

    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.

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.

FAQs

PLAXIS 2D is a finite-element software application used to model and analyze geotechnical problems.

PLAXIS is a computer application that performs finite element analyses (FEA) within the realm of geotechnical engineering, including deformation, stability and water flow. The name PLAXIS comes from PLastic and AXISymmetry, indicating the geometric types handled in the original code of the software application.

While a lots of PLAXIS 2D tutorials can be found on Bentley Communities, here are some FREE PLAXIS 2D learning resources available in our eStore.

By applying interface elements PLAXIS users can simulate the interaction between a structure and soil. While without an interface no relative displacement (slipping/gapping) will be possible between structure and soil.

When interface applied, node pairs will be created at the interface of structure and soil. Each node pair consists of two nodes – one belongs to the structure and the other belongs to the soil. The interaction between these two nodes consists of two elastic-perfectly plastic springs. One elastic-perfectly plastic spring to model the gap displacement and one elastic-perfectly plastic spring to model slip displacement.

If you want to receive tailored training or attend a PLAXIS 2D course that is specific to your project requirement, Bentley offers extra training and mentoring services. You can choose from tailor-made training, on-demand learning, consulting services, mentoring and more. Learn more about Expert Services here.

The cost of PLAXIS 2D, PLAXIS 2D Advanced, PLAXIS 2D Ultimate and PLAXIS 2D WorkSuite varies per region.
