PLAXIS 2D

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.

Modeling

• Spatial variation of preconsolidation
• Tunnel deconfinement
• CAD export
• Nonlinear geogrids: Elastoplastic (N-?) and Viscoelastic (time-dependent)
• Cross and parallel permeability in interfaces
• Polar and rectangular array
• Nonlinear embedded beam row (M-? diagrams)
• Easy definition of rock bolts in Tunnel Designer
• Unlimited combinations of point forces and distributed loads

Material Models

Calculations

• Field stress initial calculation type
• Well-proven and robust calculation procedures
• Multicore computing
• Include or exclude soil clusters and/or structural elements in safety analysis
• 64-bit calculation kernel
• Facilities for steady-state groundwater flow calculations, including flow-related material parameters, boundary conditions, drains, and wells
• Distinguish between a plastic calculation, consolidation, and safety analysis
• Automatic regeneration of construction stages

Results

• Load-displacement curves
• Use the Output command line to display plots, or save plots with user-defined resolution
• Select number of significant digits displayed
• PLAXIS 2D Viewer
• Automatic centerline extraction for structural forces plots
• Structural forces in Volumes (Tunnel lining, retaining wall)
• Resulting Force View
• Preview Calculation results
• Plot Annotations

Usage

• Rock-mass response and surface settlements due to tunneling, mining, or reservoir depletion
• Slope stability and seepage analysis for large earth dams, tailing dams, embankments, and pit mines
• Predicting differential settlements of buildings adjacent to excavation pits
• Stability of and seepage into excavation pits, lateral displacements of diaphragm walls
• Calculate necessary consolidation time for pore pressure dissipation in undrained loading problems
• Bearing capacity and foundation settlement analysis for high-rise buildings, LNG tanks, and other structures

Subscription Entitlement Service Supports

• Provides a universal ID to link together all activity within Bentley applications
  • Manage license entitlements at a user level, without requiring activation keys or hardware dongles
  • Access personal learn material, paths and history, timely product related news, automatic product updates, and notifications

Operating System

Windows 10, Windows 11

Graphics Card

Required: GPU with 256 MB OpenGL 3.3
Bentley strongly recommends avoiding simple onboard graphics chips in favor of a discrete GPU from the nVidia GeForce or Quadro range with at least 128-bit bus and 1 GB of RAM, or equivalent solution from ATI/AMD.

Processor

Required: Dual Core CPU, Recommended: Quad Core CPU

Memory

Recommended for 2D: minimum 4 GB. Large projects may require more.

Hard Disk

Minimum 2 GB free space on the partition where the WindowsTEMP directory resides, and 2 GB free space on the partition where projects are saved. Large projects may require significantly more space on both partitions.

For best performance, ensure that the TEMP directory and the project directory reside on the same partition.

Video

Required: 1024 x 768 pixels, 32-bit color palette, Recommended: 1920 x 1080 pixels, 32-bit color palette
