Ansys 2019 R3 Improves the User Experience and Autonomous Vehicle Development

Autonomous vehicle development is dominating the engineering landscape. It’s to the point where the average consumer is willing to ride in an autonomous vehicle within their lifetime.

The engineers developing these autonomous cars, planes, boats and drones are tasked to make the operation of these vehicles functionally safe. Proving this level of safety will require testing autonomous vehicles for billions of miles. That is not feasible or cost effective.

Ansys 2019 R3 focuses on providing
engineers with the solutions they need
to develop autonomous vehicles.

However, engineers can use Ansys simulation to test every aspect of these autonomous vehicles in a virtual environment — reducing development times and getting to market faster. Ansys 2019 R3 offers engineers an end-to-end simulation solution that can perform:

  • Closed-loop simulations
  • Embedded software development
  • Functional safety analysis
  • Sensor simulations
  • Human-machine interface (HMI) development

For instance, the release includes the launch of Ansys SCADE Vision, which enables engineers to evaluate the safety of autonomous vehicle perception systems.

Engineers developing autonomous systems will also benefit from the addition of:

3D Design: Reverse Engineering and Generative Design Updates

Ansys 2019 R3 introduces Ansys Discovery Live’s interactive topology optimization tool for generative design.

Discovery Live also has new simulation capabilities, including:

For those working on developing autonomous vehicles, HFSS and HFSS SBR+ now include new abilities to post-process complex radar cross sections. Additionally, HFSS SBR+ has the new ability to use creeping wave physics to predict radar cross sections of large, curved objects.

Finally, the HFSS regions in Ansys SIwave hybrid solutions can be distributed across parallel compute resources. This feature will speed up the development of integrated circuit (IC) packages and printed circuit boards (PCB).

 

Embedded Software and VR: Ansys SCADE Vision Tests Embedded Perception Software

Ansys 2019 R3 debuts Ansys SCADE Vision, which enables safety analysts, neural network developers and engineers working on machine learning to test artificial intelligence (AI) based perception software with unlabeled data. SCADE Vision finds edge cases where the autonomous vehicle system might have difficulty identifying certain objects in a traffic scenario. Also, SCADE Vision ensures that the autonomous vehicle’s perception algorithm and AI are free from detection defects.

Ansys SCADE Vision helps engineers save time and
money testing embedded perception software.

Ansys SCADE also offers engineers a complete AUTOSAR software component. As a result, engineers can import large Simulink® models into SCADE — effectively reusing legacy models produced by system engineering teams.

Additionally, engineers can apply fault-tolerant meshes to nonconformal interfaces while performing a conjugate heat transfer simulation.

Ansys Fluent can now post-process and evaluate
complex reduced-order models (ROMs).

Another user experience boost is that engineers can use the Fluent expression language with parameters, reports and monitors.

Other improvements to Ansys computational fluid dynamic (CFD) technologies include:

  • Creating organic, optimal shapes using the Fluent adjoint solver automated workflow
  • Evaluating complex reduced-order models (ROMs) using Fluent
  • Assessing conjugate heat transfer by combining Ansys Forte with Fluent or Ansys Mechanical

Selector includes a comprehensive materials data library and tools to apply this data in materials selection and analysis.

This new Selector strengthens the metals data offering by making it easier to compare, study equivalencies and select materials across global metals standards.

Electromagnetic engineers will also benefit from access to Ansys Granta Materials Data for Simulation in the Ansys Electronic Desktop. These engineers join Ansys Mechanical users in having access to many hundreds of records of electromagnetic, mechanical and thermal properties across various material classes.

 

Multiphysics: Electrothermal Management with 3D-Transient Ansys Maxwell Simulations

Engineers who use Ansys System Coupling to perform Ansys Multiphysics simulations that address electrothermal management problems can now include cases with 3D-transient Ansys Maxwell analysis. This extends the Maxwell coupling capabilities that previously included 3D eddy current and 2D transient cosimulations.

These new Maxwell multiphysics coupling capabilities will be useful to engineers working on the electrothermal management of busbars and motors.

The performance and accuracy of Ansys Multiphysics is also improved. Industrial benchmark tests show that system coupling performs 15% faster, and leads to faster cosimulations, than previous releases.

Engineers will also have access to a best-practices guide within the Ansys System Coupling documentation that outlines how to simulate two-way, fluid–structure interactions with deformations.

 

Optical: Ansys Speos Now Includes Head-Up Display Optical Design

In Ansys 2019 R3, Ansys Speos gains a feature that is dedicated to the generation of optimal head-up displays (HUD). The feature improves the legibility and clarity of the images produced by the HUD by optimizing its layout and shapes. This feature works directly in a CAD environment.

Ansys Speos can generate an optimal
HUD to improve image clarity.

The latest release of Ansys Speos also includes support for meshed geometry. This improves Speos’s integration into multiphysics workflows and the Ansys platform.

Additionally, Speos now includes an improved interface and user experience. For instance, Speos Live Preview includes the ability to switch between true and false colors with one click. Users can also quickly adjust the scale adaption and sensor type.

Speos has added sensor capabilities with the release of the Speos Road Library for Sensor Simulation. This library includes retro-reflecting materials (like asphalt, signs, paint and vegetation) that are detectable by any sensor.

The Ansys 2019 R3 release of Speos also includes the ability to:

  • Use ambient and thermal models to improve optical simulations with the sky and sun

Specifically, automotive IC designers can use Ansys PowerArtist, Ansys Totem and the Ansys RedHawk family of solutions for ISO 26262 safety-critical development projects.

Multiphysics challenges, such as power, thermal and reliability, are important to the design of advanced FinFET process nodes and 2.5/3D-IC packaging technologies. The use of these technologies in ADAS and autonomous systems is increasing. Ansys semiconductor solutions comprehensively address these multiphysics challenges across the chip-package-system. Ansys and the Taiwan Semiconductor Manufacturing Company (TSMC) have collaborated on this front to release the Automotive Reliability Solution Guide 2.0 for 7nm FinFET process technology.
