Ansys Release 2021 R2 is here!

Ansys, Inc. released the Ansys 2021 R2 on July 20, 2021. Here you can find new features and further developments across the entire application spectrum of the Ansys program family.

Engineering What’s Ahead - some highlights at a glance

Across the entire breadth of the Ansys family of programs, a couple of features have been added in Ansys 2021 R2 to help engineers optimally develop the products of tomorrow. Here is a short excerpt of new features, especially from the areas of structural mechanics, fluid dynamics and electromagnetics.

Structural mechanics

Among the new features for structural mechanics in Ansys Mechanical, the extended scripting functions for modeling have to be highlighted, as well as significant improvements, for example, to the analysis of welds, or acoustics. Streamlined multi-stage analysis with differing cyclic symmetry sector counts deliver tremendous time savings. Other program packages in the area of structural mechanics, LS-Dyna (new: e.g. Ansys Cloud support), Motion (new: e.g. contacts, acoustic interface), SpaceClaim (e.g. with new CAD interfaces), Additive Solution (e.g. with enhanced microstructures, shape optimization capabilities) and Sherlock (new: e.g. extended workbench integration, theory guide) also contain selective further developments.

CFD

In the area of flow and CFD, Ansys Fluent contains significant enhancements for applications such as supersonic flows, wall erosion and combustion. CFX calculations and animations are massively accelerated by Ansys Cloud as well as GPU support. Other program packages such as BladeModeler (new: e.g. Elastic Licensing possible), BladeEditor (new: e.g. extended blade optimization), Forte (new: e.g. coupling with Mechanical) or Rocky (e.g. new couplings with Fluent or Motion) have also been equipped with some interesting new functions.

Electromagnetics

In the field of electromagnetics, the integration of Ansys optiSLang into the Ansys Electronics Desktop has been done. The continuous expansion of the application spectrum of the leading Ansys tools for the precise simulation of a wide variety of low and high frequency phenomena has also been continued in Ansys 2021 R2. We have provided the details for you in the feature list below and will present some of them in the update webinar.

DISCOVERY, PLATFORM, OTHERS

Please note: This is only a small cross-section of new features in Ansys 2021 R2, which continues in product packages - which, by the way, have all been equipped with new product symbols - outside of Mechanics, CFD and Electromagnetics, with Ansys Discovery, Ansys SCADE, Ansys TwinBuilder or Ansys Granta leading the way. You will get a more detailed insight in the following feature overview.

Highlights in 2021R2 - Structural mechanics

Ansys Mechanical

Unlimited modeling possibilities with journaling and scripting in the Mechanical interface. Users can now embed Python scripts directly into their models.
Increased meshing efficiency and quality for shell mesh and new seam weld capabilities with the addition of heat effected zones.
Streamlined multistage analysis with differing cyclic symmetry sector counts deliver tremendous time saving by reducing the model size and run time by up to 50X.
Transient Acoustics in the Coupled Field Transient Analysis System
Automatic ‘Static to Transient’ Analysis for Nonlinear Problems

Ansys LS-DYNA

Empower users to run large jobs and overcome hardware capacity limitations with high-performance computing ARM and Ansys Cloud support for Ansys LS-DYNA.
Increased exposure of LS-DYNA technologies in Ansys Mechanical – Smooth Particle Hydrodynamics (SPH), Arbitrary Lagrangian-Eulerian (ALE), and implicit – explicit solutions that enable workflows like pre-stress loading and restarts for drop-test simulations.
LS-DYNA solver continues to add exciting new features in many areas like IGA, advanced materials, SPG, and complex multi-physics which can be used for battery-abuse modeling, electrophysiology, and many more areas.

Ansys Motion

Enhancements in contact performance within Motion solver led to up to 10X speed-up. For the Mechanical integration for Motion, ease of use of contact creation is also improved.
Automated Motion to Acoustic Interface – allows users to drag and drop harmonic acoustic system onto the results of their motion system within Workbench
Simulation Scenario permits executing an action (Stop solution, Activate/deactivate joint…) based on solution time or a functional expression.

SpaceClaim / Discovery Modeling

New license Discovery Modeling that allows running SpaceClaim, DesignModeler, or Discovery (in model stage only)
Ability to launch SpaceClaim with an enterprise license increment
New CAD Connectivity are available for Discovery Modeling enabling bi-directional coupling

Ansys Additive Solution

Faster solve times and improved user workflows for Additive Manufacturing users with improvements in Calibration Wizard and addition of Variable Layer Heights.
Increased accuracy and numerical consistency owing to changes to meshing defaults and improved robustness to Additive Manufacturing bond connections.
Significant speed improvements in Additive Manufacturing microstructure simulations by enabling users to apply more threads.
Structural Optimization now embeds several technologies: Topology Optimization, Lattice Optimization and Shape Optimization.

Electronics Reliability Highlights

Expanded Workbench integration capabilities, including the ability to start a new Sherlock project directly in Workbench and improved handling of PCBs that are combined with enclosures and housings.
Integration with Ansys LS-DYNA through a single-click automated workflow in Workbench that rapidly creates meshed models for drop-test simulations in LS-DYNA, among other analysis types.
Updated Sherlock Theory Guides are now available discussing the physics and mathematics behind Sherlock’s life predictions and failure analysis suite.
