in Detail

2022R1

Ansys Mechanical

  • Better utilization and performance with the hybrid parallel technique within the Mechanical solver. This new technique provides more flexibility and efficiency by pushing the limits of user’s hardware, memory, and simulation environment to get the most efficient runs out of a user’s available resources.
  • Pre-stressed Coupled Field Modal and Harmonic analyses for structural-acoustics, structural-electric and Piezo-acoustics.
  • Condense elements into one “super element” with substructure generation analysis. Enables users to represent their model with ROMs (reduced order models) which saves simulation time and encourages sharing models across engineering groups.
  • Faster Postptrocessing, user annotations and result probe labels

NVH Toolkit

  • Increased confidence in correlating test and simulation data with the new NVH (Noise Vibration Harshness) toolkit inside Mechanical. Users can easily read in physical test data and compute the MAC (Modal Assurance Criterion) to compare simulation data and physical test data.

Ansys LS-DYNA

  • Continued integration of LS-DYNA technologies in Mechanical to run LS-DYNA simulations more efficiently with improvements in Restart capabilities such as change in Boundary Condition support, and the modification of imposed displacements.
  • LS-DYNA solver continues to add exciting new features in many areas like dedicated Iso-geometric Analysis (IGA) cards, advanced new materials, and material laws for multi-physics applications, which can be used for battery-abuse modeling, electro-physiology, and many more areas.
  • New improvements to Smooth Particle Galerkin (SPG) enables users to achieve more accurate and fast solutions.

Ansys Motion

  • Continued work to integrate Motion into Ansys ecosystem and 3rd party tools, such as FTire. This connection help users to acquire tire data and run their vehicle dynamics jobs directly in Motion.
  • Continued Motion integration into Mechanical - stresses and strains can now evaluated in Mechanical at element nodes to improve result accuracy.
  • Solver performance improvement, up to 50% speed improvement for certain models.

Ansys Additive Solution

  • Introducing Directed Energy Deposition (DED) process simulation to the Ansys Additive Portfolio, providing capabilities from predicting macro-level temperature distortions and stresses to prevent build failures and provide trend data for improving designs for additive manufacturing including part orientation and part build order.
  • Continued improvements for Power Bed Fusion (PBF) process simulation that doubles the solver speed for scan patterns simulation, paired with an expanding material library.
  • Workflow speed improvements that include fully threaded solver support, multi-platform additive wizard support, MAPDL solver enhancements, and now providing a seamless transfer from Additive Products to Workbench and Mechanical
  • The volume of data for additive manufacturing continues to grow. To harness this trend Machine Learning capabilities have been integrated into Granta MI™ for process parameter optimization, data visualization and training. Bringing value to sparse and noisy additive data.

Electronics Reliability

  • Additional insights into PCB thermal performance with high-fidelity PCB models from Sherlock that can now be exported to Ansys AEDT Icepak for thermal analysis simulations.
  • New semi-automated Reinforcement Technology workflow automates many previously manual tasks in Sherlock, such as the assignment of reinforcement material, thickness, and type properties for traces and vias.
  • New GDSII/EDB file import capability allows users to import chip- and die-level models directly into Sherlock as a part of their pre-processing workflow.

Ansys Forming

  • Simulates metal stamping tasks through an end-to-end workflow that allows you to perform the entire die process in a single platform, easy to use GUI, with the fastest solve time.
  • Achieve optimal performance, maintain speed and accuracy, enhance your productivity and cost savings by reducing die cuts and redesign. Highly scalable SMP and MPP performance with LS-DYNA as a solver for metal stamping.
  • Significantly reduce the number of elements during simulation and speed up solve time with smart adaptivity capabilities for users to accurately refine the mesh.

Ansys Sound

  • Optimize acoustic performance and reduce noise annoyance with tonality indicators that can be calculated in display order with the ability to switch order levels. This is especially of interest to customers working with rotating machinery.
  • Fully released FRF (Frequency Response Function) capability allows users to characterize the transfer function of a system by estimating frequency response and minimize the effect of the noise at the receiver. Results can then be transferred to Fluent to filter a simulation result for more a more robust analysis.
  • New capability displays sound loudness (ISO 532-1), one of the mostly used sound quality indicators, as a colormap which enhances analysis capabilities. Users can immediately check the time (or RPM) and the frequency to ultimately reduce noise annoyance.

Notes on installation and licensing for Ansys product updates

Installation instructions

NOTES ON INSTALLATION

Since Microsoft has officially terminated the maintenance of Windows 7 as of 14 January 2020, Windows 7 is also no longer supported by Ansys. For security reasons alone, an update to Windows 10 is recommended.

The software can be downloaded as usual via the Ansys Customer Portal:
Software Download

For new customers, a user login is required before downloading. For this registration the current customer number is required.
 

To download the Ansys software, we recommend downloading the ISO images. With this download option, you will receive all data and do not have to assemble single modules to an installation archive. It is not necessary to burn a DVD, because the downloaded ISO images can also be unpacked with appropriate tools like 7-Zip (please use the latest version!) or WinRAR. Please do NOT use the Windows own Zip Utility or WinZip, because they might not unpack the images without errors. The individual ISO images must always be unpacked into their own folders to avoid overwriting files with the same name.

Further information about the current Ansys Release 2022 R1 is available in the download menu under the item "Getting Started". These notes contain information about the topics: Highlights of Release, Platform Support Documents, Important Notices, Downloads & Prerequisites, Installation;

With Ansys 2022 R1 only 64bit operating systems are supported. This applies to the licensing as well as to the client / server installation of the Ansys software. Further information about platform support is available under the following link:
