Switch to dongle-less licensing with the PLAXIS 2D and 3D CONNECT Edition V20


With the joint release of PLAXIS 2D CONNECT Edition V20 and PLAXIS 3D CONNECT Edition V20, geotechnical analysis enters Bentley’s CONNECTED Data Environment (CDE): an open, integrated framework to enable collaboration, improve decision making, and deliver better project outcomes and better performing assets. Bentley’s open CDE supports collaborative digital workflows, where data captured or created for one purpose can also be used by other applications thereby saving time, minimizing rework, and improving data quality over the asset lifecycle.

Subscription Entitlement Service (SES) Licensing

The new PLAXIS releases use the same licensing system as the rest of the applications in your Bentley Playbook. SES Licensing provides a unique ID throughout all Bentley applications, removing the need for dongle keys and manual license version management. Additionally, access personal learning material, paths and history, timely product related news, automatic product updates, and notifications.

Learn more about the new PLAXIS licenses, transitioning to SES, and combining CONNECT Edition and legacy versions in the PLAXIS Wiki section of Bentley Communities.

Loft polycurves and Blend surfaces

Both these tools can be used to provide smooth transitions between non-homogeneous sections. The ‘Blend surfaces’ generates a continuous surface that joins together a set of other surfaces by “filling the voids” between them. The ‘Loft polycurves’ command fits a surface to a set of polycurves, for example to turn a series of spatially-located 2D cross-sections into a consistent 3D geometry.

Girder definition in tunnel designer

Tunnels are often reinforced with transverse ribs. These can now be modelled as curved beam elements located at specific intervals in the 3D Tunnel Designer. The option to add transverse girders, together with plate and volume lining, rockbolts, and umbrella arches, enables modelling complex tunnel reinforcement systems. Girders are a natural component in the slicing and sequencing features of the Tunnel Designer, enabling you to define the entire construction sequence.

NURBS curves

Use NURBS curves to model arbitrary shapes in 3D. NURBS curves are automatically generated from a series of successive points. NURBS curves and polycurves can be combined to generate almost any geometry. NURBS curves can also be specified as extrusion paths, which enables generating curved linear elements with uniform cross-section. For example, a cross-section defined by a polygon or polycurve can be extruded along the trajectory defined by a NURBS curve.

Line pass / Cross section curves

Create cross-section curveplots from any arbitrary line cross-section, structural element or centerline generated from the Structural forces in volume piles tool. This allows you to for example create a single curveplot to compare how the settlements at the surface level evolve for multiple phases, or to compare the bending moment along the length of a diaphragm wall or tunnel lining (either modeled as plates or volume elements) across multiple phases at once.

Field stress per cluster

The Field Stress initial calculation type allows directly specifying in situ stress conditions on a volume of soil. It is now possible to assign a different field stress property to individual soil volumes and borehole layers, allowing you to independently input the initial stress state by magnitude and orientation for each of those clusters. The cluster-based field stress complements the global field stress and makes it easier to define the in-situ stress for geological models. This allows easily modelling non-uniform deepground conditions, such as those encountered in deep tunneling or reservoir geomechanics.

Dynamic with consolidation calculation type

Simulate the coupling between soil deformations and transient seepage in the dynamic loading phase of PLAXIS 3D with the new advanced calculation type ‘Dynamic with consolidation’. Using this calculation type offers generally improved stress predictions and accounts for both eventualities of accumulation and dissipation of excess pore pressures during earthquakes.

Scriptable SoilTest

In our effort to provide easier and more powerful scripting capabilities, the SoilTest module for PLAXIS 2D and 3D now has its own command line interface, which can also be called from the Remote Scripting API. You can now automate the simulation of laboratory tests in order to fit the material model’s parameters. Happy scripting!

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.

ISM Interoperability (Technology Preview)

Import structural geometries and properties from a Bentley Integrated Structural Modeling (ISM) repository. ISM allows you to share structural engineering information among modeling, analysis, design, drafting, and detailing software applications. Perform design reviews across your entire team with seamlessly integrated 3D applications and BIM platforms and synchronize changes over time. ISM facilitates interoperability across engineering teams and design disciplines, allowing designers to choose the products best suited for a particular project. With ISM-based workflows you can:

  • Exchange data
  • Synchronize revisions
  • Track progress
  • Compare alternatives
  • Publish deliverables

STAAD.Pro Coupling Tool (Technology Preview)

Bridging the gap between structural and geotechnical engineers, the PLAXIS Coupling Tool is available now for STAAD.Pro directly within PLAXIS 3D. Through the Coupling Tool you can select load cases from STAAD and have the loads at the bottom of the structural model transferred directly onto the subsurface model in PLAXIS 3D. In the coupling process, the calculated displacements in PLAXIS are sent to STAAD in the form of updated spring stiffnesses, after which STAAD recalculates the resulting displacements and forces in the structural model. The process is repeated until balance is found.
