PLAXIS 2D/3D CONNECT Edition V2023| 4.5 Gb
Updated: Added PLAXIS 2D CONNECT Edition V22 Update 2 The PLAXIS development team is pleased to announce the availability of PLAXIS 2D/3D 2023.2 (23.02.00.1079). Perform advanced finite element or limit equilibrium analysis of soil and rock deformation and stability, as well as soil structure interaction, groundwater, and heat flow. The latest releases of PLAXIS marks our definitive transition to becoming part of Seequent, The Bentley Subsurface Company, with some minor cosmetic changes and a change to the version numbering. Benefit from workflow enhancements for rock and mining engineers, a new material model and SoilTest options for users working with unsaturated soils. PLAXIS 2D enters the world of subsurface digital twins and PLAXIS Monopile Designer users can improve their designs with additional design criteria. What's new in PLAXIS 2023.1 Import of Leapfrog cross sections from Seequent CentralWith PLAXIS becoming part of Seequent, our products can start offering much tighter integration and workflows for subsurface digital twins. The first step of this integration is through the new Import geometry from Central option in PLAXIS 2D. The workflow involves Leapfrog Works or Leapfrog Geo as a starting point, to create a 3D geological model from the incorporation and interpretation of digital site investigation data. Once the 3D Geological model is completed, the model can then be sliced with arbitrary cross sections or a sequence of cross sections intervals along an alignment, or path.
The 3D geological model and the cross-section can then be published to Seequent’s cloud based visualization and collaboration solution Central. The full project now hosted on Central acts as a single source of truth. Collaborators can download the latest copy of the model from Central and independently modify, update, and republish the model as a newer instance of the project.
The cross sections published in Central can be accessed through PLAXIS 2D with the Import geometry from Central option. The user will be prompted to select the relevant server, project and latest published data and can then choose one of the available cross sections. Once chosen, the application will download the cross-section data and open the import dialog window to show the polygons that will be imported. Once accepted by the user, the geometry will be inserted into the project. The user can then proceed to add structural elements and loads to the PLAXIS model as usual. The new Central icon on the main task bar will reflect the status of the geometry inside PLAXIS. If someone publishes a new instance of the Leapfrog project into Central, PLAXIS will be notified by Central. The user can then verify if there are any geometric changes to their cross section and can choose to reimport the data if so. This way the user can always be informed on whether the latest geological information is used in the project and make it much easier to recognize and import that data from a verified single source of truth. Check out the movie below showing the entire workflow for a drift in an underground mine complex:
Barcelona Basic model
The Barcelona Basic model (BBM) is a Cam-Clay type effective stress model for the behaviour of unsaturated soils. The PLAXIS version of the BBM is defined in terms of Bishop effective stress and suction as stress variables, with an improved yield surface to capture better stress triaxiality both for saturated and unsaturated soils. The most important features of the model consist of the capabilities to model both elastic swelling and irreversible 'collapse' deformation upon wetting, as well as shear strength decrease when suction is reduced. Therefore, the model is most suitable for collapsible and/or moderately expansive soil, such as low plasticity (silt, clayey sand, etc.) and granular unsaturated soils. The Barcelona Basic Model was implemented with scientific support from the Polytechnic University of Catalunya (UPC), where the model was originally developed. This support is gratefully acknowledged. The model is available in the Advanced and Ultimate tiers with a valid Geotechnical SELECT Entitlement.
Temperature and Suction in SoilTest
The SoilTest facility now has the option to account for an initial temperature and/ or suction for almost all the test types, except the Pressure meter test type. For the General test type, temperature and suction increments can be defined per test phase to replicate real life lab tests during which the temperature and/ or suction are varied. After calculating a SoilTest, some new standard graphs are automatically added, showing the evolution of temperature and suction versus strain. These new options, available in SoilTest under the Options menu, allow users to calibrate model parameters for the more advanced material models in PLAXIS that may be derived from suction or temperature-controlled lab tests, like the Barcelona Basic Model or the Frozen/Unfrozen Model. While temperature support in SoilTest is only available for PLAXIS 2D Advanced or Ultimate with a valid Geotechnical SELECT entitlement, suction in SoilTest is available for the 2D and 3D Advanced or Ultimate tiers with a valid Geotechnical SELECT Entitlement.
Cable bolt in Tunnel Designer
The tunnel designer has been updated to include the Cable bolt element when defining the reinforcements. After adding reinforcements to a tunnel segment, the user can now select from a new drop-down menu called "Element type" in the property tree of the Reinforcements tab. A choice is given between "Cable bolt" or "Rock bolt". The former uses the new Cable bolt element, the latter still uses the approach of previous releases namely the embedded beam element. Some objects and bolt configuration options have been renamed, fully changing the command and scripting signature which affect the backward compatibility of existing scripts. With the Cable bolts now available in the Tunnel Designer it makes it much easier to define reinforcement patterns involving cable bolts, but also to change the properties of these patterns, like length, spacing or number of cable bolts, allowing the geometry changes to regenerate with the click of button.
Small enhancements and fixes
Decompose into segments command
PLAXIS 2D offers a new right mouse button context menu option called Decompose into segments that explodes polycurves into individual line segments. The individual line segments can then be assigned features, i.e. loads, interfaces, etc., also through the right mouse button. Since the original line is then used to assign the feature, the user can be ensured that no drawing mistakes were made. Together with the Create Polygon option introduced in the previous release, it makes working with imported geometry much more friendly and provides the user with more accurate model input.
SumPhase displacements for plates
From this release on, the way the SumPhase displacements for plates in PLAXIS 2D and 3D are presented have changed. This will now show the deformation results of the plate, or subpart, only since its activation, and so is more in line with user expectations and makes it easier to inspect and extract results for reporting or plotting purposes.
Due to this change, when opening a project calculated in a previous release, the SumPhase displacement results for plates (only) will show N/A. The project should be recalculated in this latest release in order to get the SumPhase displacement results for plates in the new format. Other results are unaffected by this change.
Solved known issues
We fixed an issue in the PLAXIS Output Report Generator when including different structural material types
Discontinuities in PLAXIS 3D
CAD Improvement - importing polycurves as polygons In PLAXIS 2D, geometry from CAD files is typically imported the same way as it is defined in the CAD file. This means that polylines, whether closed or open, will normally be imported as polylines and lines as lines etc. However, in CAD drawings the closed polylines usually represent soil/rock clusters or structures like quay walls etc. and users will expect these to be recognized by PLAXIS as soil/rock/structure polygons. This goes very well when users assigned so called Regions or Boundaries to their CAD drawing before exporting it from their drawing tool.However not every software, for example Leapfrog, supports the creation of Regions or Boundaries, therefore importing CAD drawings that contain closed polylines into PLAXIS 2D would sometimes require the user to manually trace the imported polylines to create polygons. In this latest release the interoperability with CAD packages becomes much easier and more robust better by introducing the "Import closed polylines as polygons" option in the import window. When activating this option in the import window, the GUI will show all the polygons that will be created and once accepted, the only thing left to do for the user is to assign the materials to the automatically created soil/rock polygons. Design Approaches - Side panel warnings and improved validation checks
Design Approaches feedback details in PLAXIS 2D When editing soil materials in the Materials window, the side panel will now give warnings and errors about potentially invalid parameter combinations when combined with a created Design Approach and its applied material factors. In addition, the validate <material> command has been extended to include the feedback for the potentially invalid parameter combinations when combined with a created Design Approach.
Design Approaches command feedback details in PLAXIS 2D The pre-calculation checks have also been improved and now give a better indication of the phase, material and the Design Approach that cause an invalid material set that blocks the calculation. This information is also available through scripting (validate and checkcalculationconditions) allowing users to ensure their applied Design Approaches are valid when generating models through scripts, before launching the calculation.
Calculation warnings on Design Approaches in PLAXIS 2D Command for Cross-section results When creating a line or planar cross-section in PLAXIS 2D or 3D, all the results for the created cross-section are stored in tables accessible through the GUI, but for scripting these results were not available. Users had to manually loop over coordinates that would outline a cross-section to retrieve the relevant result. With the new getcrosssectionresults command it's much easier, as users can now directly retrieve results from created cross-sections and access the results that are stored in the cross-section table.
Using the new getcrosssectionresults command in PLAXIS Output Solved critical issues in PLAXIS CONNECT Edition Version 22 Update 1 In this release, we fixed some critical issues from PLAXIS CONNECT Edition Version 22.00: - Solved: PLAXIS Design Approach partial factor not applied to material parameters when loading older files- Solved: Fixed an issue in the calculation manager that prevented proper saving of the files when the calculation was finished- Solved: Staged construction information on the embedded beam connection was not always correct. To avoid confusion, the information is currently hidden, and should be reviewed in structures mode.- Solved: Some Output results may not consider project units in PLAXIS CONNECT Edition V22.00PLAXIS 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.
