PLAXIS 2D程序包含2D动力（Dynamics）模块和2D渗流（PlaxFlow）模块，共同组成有限元程序包，用来进行岩土工程二维变形和稳定分析。PLAXIS 2D包是强大稳定而易于使用的有限元程序，专门针对岩土工程应用而开发。程序为今日和未来高技术建筑提供了复杂项目分析所需要的专业工具。

岩土工程软件需要先进的本构模型来模拟岩土的非线性、时间相关和各向异性的行为。而且，既然岩土是多相材料，需要特别的方法来处理土中的静力和非静力孔隙压力。尽管模拟土自身是一个重要问题，但非常多的项目还会涉及到模拟结构以及结构与土的相互作用问题。

The PLAXIS product team has unveiled PLAXIS 2D CONNECT Edition V20 is a powerful and user friendly finite element package intended for two-dimensional analysis of deformation and stability in geotechnical engineering and rock mechanics.

PLAXIS 2D CE V20.00.00 Release notes - Release: August 2019

New and improved features

Scripting Reference manual as a Jupyter notebook

- Easily learn Python-based remote scripting in PLAXIS with the new Scripting Reference manual. Sample scripts for each of the commands in PLAXIS 2D and 3D are offered in a Jupyter notebook. These samples can be run live in the software to see and understand what happens. You can also edit and rerun the samples and see the effect of your changes, offering a great way of learning-by-doing.

Others

- To improve the support for scripting, material properties can now be set to an invalid state without directly getting an error message. The calculation still needs a valid dataset;

- A new validate command for materials was added which checks every property at once;

- PLAXIS Soiltest now supports command line and remote scripting;

- the checks in the checkgeometry command have been extended. In addition, it is now also possible to execute this command from the calculation modes;

- added command for checking the calculation conditions. These conditions are now also checked when running the calculate command;

- added interactive documentation for Python scripting layer (Python Notebooks);

Fixed issues

- Interface pore pressure generation when adjacent soil uses Interpolate pore pressures is now been resolve;

- Display of plastic points could lead to an error. This is now resolved;

- Various meshing issues have been resolved;

- Other minor issues

PLAXIS Geotechnical Finite Element Analysis Software

Conquer any geotechnical project with confidence using PLAXIS. Design and perform advanced finite element analysis of soil and rock deformation and stability, as well as soil structure interaction and groundwater and heat flow. You will have what it takes to handle advanced constitutive models for the simulation of the nonlinear and time-dependent behavior of soils. Apply hydrostatic and nonhydrostatic pore pressures, model structures and the interaction between the structures and the soil, and take on projects of all types such as excavations, foundations, embankments, tunnels, mines, dredging, and more.

PLAXIS 2D

is a powerful and user friendly finite element package intended for two-dimensional 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. Applications range from excavations, embankment and foundations to tunnelling, mining and reservoir geomechanics.

PLAXIS is equipped with a broad range of advanced features to model a diverse range of geotechnical problems, all from within a single integrated software package.

PLAXIS uses predefined structural elements and loading types in a CAD-like environment. This empowers the user with fast and efficient model creation, allowing more time to interpret the results.
