New in PLAXIS 2D 2024.1
Release: February 2024
PLAXIS 2D 2024.1 (24.1.1060) contains the following improvements and updates compared to PLAXIS 2D 2023.2:
Compatibility notes: Due to the major changes in the material database and the unit system, PLAXIS 2D 2024.1 will be installed alongside Version 21, instead of overwriting it. When opening PLAXIS 2D V21 projects with PLAXIS 2D 2024.1, projects will automatically be saved as a converted copy with the
_converted suffix and will require recalculation. When using non-SI-units, the mesh also needs to be regenerated.
The PLAXIS 2D CONNECT Edition V21 projects will remain unchanged.
Earlier versions of PLAXIS
will not be able to open files saved in PLAXIS 2D 2024.1.
New features
Combined reinforcements in Tunnel designer
The tunnel designer's reinforcement definition has been extended with the option "Number of parts". This allows users to easily extend the number of line segments to a maximum of 2, for each added reinforcement pattern and then set different element types and properties per part. With 2 parts users can quickly generate a cable element consisting of 2 parts of different length, allowing later pre-stressing 1 of the parts separately from the other part in Staged construction mode, or allowing different material sets per part. Another option is generating combined reinforcement consisting of a node-to-node anchor and a connected rock bolt.
Import multiple evaluations of a cross section from Seequent Central
A single cross section in Seequent Central can contain multiple different objects that have been evaluated on the cross section in Leapfrog. These could be different geological models, meshes, volumes, designs etc. When importing a cross section from Central into PLAXIS 2D, the user can now make a multi-selection of available evaluations found under the selected cross section, as an easy way to simultaneously import different types of data available and have them correctly placed in the geotechnical model.
Fixed issues
A large number of issues have been addressed, including:
- [379073] Added indicator to PLAXIS Output title bar when the remote scripting server is activated for transparency of application status
- [379216] Fixed an issue with the installer when having the previous installation in a non-default path.
- [669788] Introduced a threshold stress for the N2PC Rock Creep model, below which creep strain does not develop. Caution when loading older files with this rock model.
- [700959] Improved the behaviour of dialogue to define the structural forces from volumes geometry.
- [701555] Improved timing for the PLAXIS Output API when quering Legend data after switching phase or the shown result type.
- [909056] Improved output command to zoom in cross-section plots in PLAXIS 2D Output
- [992870] introduced proper refence to the material index for Output result types to be used in result automation
- [1015620] Fixed an issue when choosing Create water level and continue that uses time-dependent head data for the phreatic level.
- [1066733] In some cases, after running the calculation, some files were locked and this prevented saving. This is now resolved.
- [1100505] The Python API can now retrieve all Output State Parameter values, not only the first one in a model
- [1102724] Fixed an issue with Fourier transformations that could lead to negative values.
- [1173611] Reintroduced the specific storage Ss parameter as a read-only property in the Soil material dataset window when working with Drained, Undrained A and Undrained B material types.
- [1176120] Fixed a unit issue in the calculation progress screen for the time display when using seconds as your project time unit.
- [1186210] Saved views in Output are now properly stored when using Japanese or Chinese characters.
- [1186215] Saved views in Output are now properly loaded when using Japanese or Chinese characters.
- [1207173] Removed the word Plate from Embedded beam result types in the Python API for structural results for rotations.
- [1215622] Fixed a crash in the report generation when including phase displacements for plates in a table in the final report.
- [1236424] Improved limits in Norsand pseudo-time stepping according to Sloan et al., (2001) to improve stress integration.
- [1244058] It is possible again to use a K0 larger than 1 in PLAXIS SoilTest (e.g. in triaxial test)
- [1274988] Tables for cross-section data show the assigned material name again instead of "No Soil".
- [1291581] Fixed a PLAXIS Output printing issue for anchor materials when you have a mix of elastic and elastoplastic anchor material sets.
- [1292604] Python API: fixed an issue with opening Soiltest from PLAXIS and setup SoilTest's server (s_t) and global (g_t) using the new_server function.
- [1311818] In some complex cases, the Tunnel Designer would lead to some empty data values, which would crash when loading the file. This is now fixed.
- [1312107] Improved continuation of Dynamics phases using Free Field elements and deactivating them in the next Dynamics phase.
- [1318371] Python scripting PLAXIS Input: When not checking the option, hide on startup, the license window would always pop up. This can prevent automation workflows, as this window needs to be manually accepted in that case. This can now be solved using a newly introduced command line option: when launching PLAXIS Input, use the command line argument --NO_LICENCE_INFORMATION to suppress this window. Note: this will automatically accept any license selection without confirmation.
- [1321996] Renamed the pore pressures option Interpolate to Interpolate (vertically) to explicitly explain how the interpolate is applied.
- [1334652] Updated documentation of NorSand to explicitly mention that the "innercap" yield surface is not included in the PLAXIS NorSand implementation.
- [1335530] Output visualization: now shows proper connection with tunnel lining (plates) in the deformed mesh plot.
