PLAXIS is available in three flexible options, each adapted to the different geotechnical analysis needs of any company. More information on PLAXIS 2D, PLAXIS 2D Advanced and PLAXIS 2D Ultimate can be found in our data sheet.
By engineers, for engineers, PLAXIS 2D is the finite element analysis application for soil, rock and associated structures.
Every project is challenging, but geotechnical analysis doesn’t have to be. PLAXIS 2D gives you the power of fast calculations. Perform advanced finite element or limit equilibrium analysis of soil and rock deformation and stability, as well as the interaction of soil structure, groundwater and heat flow.
Bentley’s PLAXIS 2D comes with far-reaching functionality, an unparalleled choice of constitutive models and natural geotechnical engineering workflows for best-in-class geotechnical analysis and modeling.
Product levels
PLAXIS 2D: PLAXIS 2D includes all the essential features to carry out daily deformation and safety analysis of soils and rocks without considering drag, groundwater in stable condition or thermal flow, consolidation analysis or any time-dependent effects.
PLAXIS 2D Advanced: PLAXIS 2D Advanced includes all the features of PLAXIS 2D and offers more advanced features and material models to consider drag, flow coupling and deformation through consolidation and heat flow analysis or steady-state groundwater. It also solves problems faster with the multicore solver.
PLAXIS 2D Ultimate: extend the capabilities of PLAXIS 2D Advanced with complementary features to analyze the effects of ground vibrations (such as earthquakes and traffic loads), simulate complex and time-dependent hydrological variations of water levels or flow functions at the boundaries of the soil or model, and also evaluate the effect of transient heat flow on the hydraulic and mechanical behavior of the soil.
PLAXIS 2D WorkSuite: PLAXIS 2D WorkSuite is the most comprehensive PLAXIS 2D option, as it includes PLAXIS 2D Ultimate and PLAXIS 2D LE. PLAXIS 2D WorkSuite integrates the advanced and intuitive finite element and limit equilibrium analysis features of PLAXIS applications for the development of projects and analysis of soils, rocks and associated structures.
Useful Information
Operating System
Windows 10 or Windows 11
Video card
Required: 256 MB GPU with OpenGL 3.3
Bentley does not recommend the use of integrated video cards. We recommend a dedicated GPU from nVidia’s GeForce and Quadro lines with at least 128-bit bus and 1 GB of RAM (or an equivalent solution from ATI/AMD).
Processor
Required: Dual Core CPU. Recommended: Quad Core CPU
Memory
For 2D, a minimum of 4 GB is recommended. Larger projects may require more memory.
Hard disk
Minimum 2 GB of free space on the WindowsTEMP directory partition and 2 GB of free space on the partition for saving projects. Large projects can require much more space on both partitions.
For best performance, the TEMP directory and the project directory should be on the same partition.
Video
Required: 1024 x 768 pixels, 32-bit color palette. Recommended: 1920 x 1080 pixels, 32-bit color palette
Plaxis is a computer application that performs finite element analysis (FEA) in the field of geotechnical engineering, including deformation, stability and water flow. The name PLAXIS comes from PLastic and AXISymmetry, indicating the geometric types dealt with in the application software’s original code.
