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.
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.
