Electromagnetic Updates for Autonomy, 5G, Electrification and Energy Applications
Ansys 2020 R1 improvements to the Ansys electromagnetic portfolio focus on helping engineers design and place antenna and antenna arrays for autonomous vehicle, 5G, electrification and energy applications.
As an example, Ansys offers a solution for the analysis of antenna arrays that are used in diverse applications (such as 5G mmWave base stations and microcells). This technology, known as the 3D component domain decomposition method (3D Comp DDM), empowers engineers to efficiently solve large and complex antenna array problems.
Additional highlights include improvements that enable Ansys HFSS SBR+ to assess creeping wave physics. This increases the accuracy of installed antenna analysis and placement studies when curved surfaces are involved.
Additionally, harmonic force coupling features in Ansys Maxwell will enhance the vibroacoustic and electromagnetic design of electric vehicles, transformers, turbomachinery and more.
Other electromagnetic improvements in Ansys 2020 R1 include:

Speed Up the Design and Generation of Embedded Software for Automotive and A&D Industries
The Ansys 2020 R1 upgrades to Ansys SCADE software speed up the design and automatic code generation of embedded control software. This embedded software, which is DO-178C certified and ISO 262626 ASIL D-compliant, can then be used to control vehicle components for the aerospace and defense (A&D) or automotive industry.
For instance, the release streamlines the design and workflow integration needed to create embedded software for avionic cockpit display systems that meet the ARINC 661 standard.
Some of these upgrades include:

New Fluid Workflow Helps Users Solve Multiphase Simulations
Ansys 2020 R1 continues to make computational fluid dynamics (CFD) easy with new improvements to the Ansys Fluent user experience. These improvements enable both experts and novices to use CFD simulations.
For instance, the newest workflow helps users set up multiphase simulations within a single, tabbed panel. In tests, the workflow walked users through the creation of gas‒liquid pipe flow simulations.
These users created the simulations 25% faster than they could before.
Fluent also has an algebraic interface area density (AIAD) model that can simulate transitions between continuous stratified flows and dispersed flows — like multiphase flows in a water pipe. This model is well suited to assess safety critical applications in:
Nuclear reactorsOil and gas pipelinesSteam generatorsRefrigeration equipmentReflux condensersPacked columnsHeat pumps
The AIAD model can also be used with a third phase and mass transfer mechanisms to accurately simulate entrainment and absorption. It can also be combined with a population balance model to simulate bubbles and droplets.
Finally, a new immersive graphical user interface (GUI) for Fluent will enable users to interact directly with models and graphical elements. Users will be able to edit boundaries using popups that are accessed by clicking on the model.
Other CFD updates in Ansys 2020 R1 include:
An electrochemistry model that optimizes lithium-ion battery cellsAn Ansys CFX upgrade that doubles the speed of harmonic analyses that determine base frequenciesA faster and easier method to set up two-way fluid-structure interaction (FSI) simulations

Semiconductor Power and Reliability Solutions for Complex Autonomous Driving, 5G and AI
Trends like autonomous driving, 5G and artificial intelligence (AI) are increasing the demand to signoff ultra-large and high-performance system-on-chips (SoCs). As a result, Ansys 2020 R1 includes upgrades to Ansys’ semiconductor portfolio of power and reliability solutions that improve signoff coverage and time to market.
Key features for the automotive market include foundry certifications, multiphysics flows (including thermal and electronics reliability) and ISO 26262 certification of the Ansys RedHawk family, Ansys PowerArtist and Ansys Totem.
To maximize the potential for power savings, Ansys PowerArtist features static power efficiency checks that serve as early signoff criteria that can qualify register-transfer level (RTL) designs without requiring vectors. In addition, PowerArtist accelerates power profiling of emulator-generated application activity scenarios, reducing the risk of missing power-critical cycles.
The release adds new features for 5G semiconductor and electronics design, including 3D integrated circuit (3D-IC) and advanced process node support for Ansys RaptorX and Ansys RedHawk-SC.
Ansys RaptorX improves performance and capacity by over a factor of five. It also supports advanced layout dependent effects, complex packaging structures and stack-up scenarios.
Additionally, the new Ansys RedHawk-SC no-propagation vectorless (NPV) dynamic analysis software can identify power grid weaknesses in the absence of simulation vectors. It enables greater than 90% switching coverage to achieve increased signoff confidence. RedHawk-SC also includes advanced package simulation improvements for on-die power integrity analysis.
The Totem and Redhawk product families are certified to perform multiphysics signoff for a diverse number of fin field-effect transistor (FinFET) nodes down to 4nm/3nm and 2.5D/3D-IC packaging technologies.
Additionally, Totem features enhancements for power management integrated circuits (PMIC), which are critical for automotive, mobile and data center applications. Enhancements include improvement in performance, capacity and increased out-of-the-box accuracy for high current, high power devices. The runtime has improved by a factor of four to five while maintaining a memory footprint that is 20% to 40% of traditional finite-element method (FEM) solutions.
Streamlined Workflows that Can Assess Large Nonlinear Structures
Ansys Mechanical is getting upgrades in Ansys 2020 R1 that improve its ability to process complex, highly nonlinear and massive models.
AQWA, a hydrodynamic analysis tool, is now fully migrated into Ansys Mechanical. As a result, users have the ability to model liquid filled internal tanks and transfer the loads they generate to other analysis systems. This is ideal for those designing offshore systems. This new functionality is available on Linux and enables cluster-based solving.
Mechanical will also have a series of streamlined workflows that include:
Enhanced interface integrations with LS-DYNACross sectional assignments for line bodiesPost-processing of reinforcementsDrag and drop of external models
Additionally, users will notice improvements to the topology optimization validation workflows that enable them to quickly get from a tessellated optimal shape to a mesh to a final design validation.
If users then wish to print these shapes, they can use Ansys Additive Prep to optimize the laser parameters of an additive manufacturing machine. They can then assess its inherent strain using Ansys Workbench Additive.
Other additive manufacturing improvements include:
New printable materials that are compatible with Ansys Additive Print and Additive Science.New Additive Prep compatibility with EOS machines
As for Ansys Sherlock, it will have faster solve times because of the integration of MADPL as its default solver. Additionally, Sherlock now enables users to configure and manage multiple part libraries.
New Systems Simulation Tools to Simulate Light and Ensure Cybersecurity
Ansys 2020 R1 includes two new systems simulation solutions: Ansys VRXPERIENCE Light Simulation and Ansys medini analyze for cybersecurity.
VRXPERIENCE Light Simulation delivers engineering-grade light simulation to studio designers. The solution combines the functionality of Autodesk VRED’s design visualization software and Ansys’ physics-based lighting simulations. This enables users to design and engineer photorealistic visualizations of a vehicle’s interior or exterior lighting.
As for Ansys medini analyze for cybersecurity, it gives users the ability to systematically analyze and assess security threats to their system designs. Users can then use the original offering — Ansys medini analyze — to ensure that their systems comply with the new safety of the intended functionality (SOTIF) standard. These tools will be a big part of assessing the safety and cybersecurity of autonomous systems early in their development.
The release also includes the Ansys Twin Builder Battery Wizard that guides users through the virtual construction of battery cells, modules, models and parameters.
