Electrification is everywhere! It brings energy efficiency into systems and also helps add new smart functionalities to products. The electric motor is a key element of such systems, converting electricity into mechanical power. It is multiphysics by nature. Electric machine engineers need to take into account various constraints from the early stage of the design, looking at electromechanical performance, as well as respecting thermal and NVH constraints. Simulations need to integrate these multiple physics and also coupling effects. Dedicated tools and streamlined multiphysics workflows are developed in order to reduce complexity and speed up the design.

This presentation is an overview of Rizel Automotive’s R&D journey towards developing an efficient and cost-effective Motor Platform with optimum characteristics for the automotive EV Space using Altair’s tools to solve electromagnetic, structural, NVH, and Thermal challenges and validate the Digital Designs and through Physical Testing. All the way through the design process, Altair tools helped us in solving the complex problems which solve the core electric motor problems; like inductances calculation, cogging torque optimization, D axis conditioning, model analysis, transient thermal analysis which helped us in understanding and validating our analytical design and research. With the help of Altair tools, we were able to implement and validate our novel ideas related to thermal design and come up with a unique motor architecture without compromising on electromagnetics. In this process, we have designed one of the lightest and compact radial flux motors in the industry. Easy to use software from Altair, with a simple interface and automation tools; helped us to iterate, fine-tune our motors with high accuracy and a much quicker pace. And helped us to engineer a powerful yet silent and cooler but efficient motor. From our recent dyno testing at ARAI, we were able to match the simulated data to dyno test results with a deviance of less than 5%, giving us great confidence in our Simulation Techniques and Altair’s tools, helping us decrease the Time to Enter the Market.

Sustainable designs last longer. David Yáñez from Vortex Bladeless, a Spanish start-up, shares his vision of the technology, the strategies used for the integration of the different physical phenomena involved in the simulation-driven design, and the development of their resonating structures having minimal parts susceptible to wear by friction. The simulation results from CFD, with fluid-structure interaction, and electromagnetic field simulation are compared with experimental wind tunnel results and from in-service environments.

An intuitive and robust CFD workflow is available in Altair® SimLab® - a process-oriented, feature-based finite element analysis software that allows you to quickly and accurately simulate the engineering behavior of complex assemblies. For fluid and thermal analyses, SimLab can make the model setup process even faster, repeatable, thereby minimizing tedious manual steps that can be automated. A live demo will be performed using real-world models to show the simple and smooth analysis process in Altair SimLab that goes from CAD to results in minutes.

AAM has been providing mechanical drivelines to automotive customers for more than 25 years. As the automobile transitions to electrification, so too must the driveline. AAM has developed a suite of innovative, lightweight, compact and cost-optimized electric drive units and electric beam axles to meet the growing global technology demand as electric vehicles continue to expand over the next decade. Engineering simulation, optimization and validation tools were significant enablers to increase the validation confidence and reduce the time to market for these new products.

The increasing complexity of machines requires active management and evaluation of potential product failures and simulation of physically accurate conditions during development. Achieved through multiphysics simulation, Altair SimLab can simulate a wide range of interacting physical models including fluid-structure interaction (FSI) and thermomechanical simulation. By helping with complex design problems, simplified modeling workflows give a deeper understanding of phenomena and root causes of unwanted behavior.

To design today’s tightly packaged electronic systems it is essential to create a thermal analysis model of the PCB within its enclosure. Learn how Altair SimLab provides robust and repeatable workflows for fast, accurate, and consistent analysis, even for occasional users allowing them to confidently identify and correct potential design issues earlier in development with accurate thermal analysis that doesn’t require advanced CFD knowledge.

The ever-advancing digitization is being driven by the convergence of simulation, data, and HPC. While virtual methods, interoperable tools, and standardized interfaces become state of the art, the engineers and their management will play a significant role to break down silos and benefit from a Digital Thread. In this fireside chat, we will discuss the importance of people to unleash the potential of Digital Twins, how they can combine the different fields of product development and what is still missing to make the connection.

For the past three decades, Altair’s optimization solutions have driven the innovative, lightweight, and structurally efficient designs of many products you see and use every day. The intense focus on additive manufacturing in recent years have given a boost to topology optimization and generative design, providing more freedom to explore alternatives. Today, we keep on innovating the technology, looking at including multiple physics, like thermal, electromagnetics, and fluid flow to drive design. Altair AcuSolve – coupled with Altair Optistruct – enables engineers to find the optimum shape by simply defining inlets, outlets, and the allowable space in which the solver can work. AcuSolve’s gradient-based topology optimization method will quickly and efficiently find the path of least resistance to deliver fluid flows with minimal effort.

Gaining insights into a product’s performances has never been easier. With the HyperWorks Design Explorer, users can easily set up and execute the design of experiments (DOE) and optimization studies, learning which attributes contribute the most to the different performances, review, plot, and compare results from multiple runs, and ultimately identify optimal designs. The quick and easy setup process is solver independent, yet fully integrated with Altair’s structural analysis solutions. On the other hand, many design specifications are quantifiable and can be confirmed by physics but optimizing a design for subjective design requirements such as the look and feel of a product requires a different approach. This is when expertAI can help. It uses machine learning to enable you to include criteria that have traditionally been considered purely subjective or expert-driven in design optimization. The AI algorithms cluster your designs with respect to their subjective behaviors allowing them to be labeled to train a model aligned with your preferences.

Altair products are quickly evolving into AI-driven products. Starting from the modeling and visualization products, the latest release of Altair HyperWorks includes features like shapeAI, which quickly finds and classifies parts “by shape” inside geometry files or finite element meshes - when you want to locate all of the bolts, shafts, and gears in a complex assembly - by applying machine learning.

At Altair, we see a future where seemingly disparate systems work seamlessly together to help businesses succeed. Where pin-point accuracy and speed mean the difference between winning and losing. The world of data science is intersecting with high-performance cloud computing, artificial intelligence, and IoT, unlocking limitless potential and enabling enterprises of all sizes to compete on a global scale while creating a more sustainable future.

What makes artificial intelligence a game changer is not what movies depict with the loud destructive powers of artificially intelligent robots. It’s the opposite, it is the silent creative destruction that it brings as apps in our phones or features in the tools that we use such as spam filters, fraud detectors, and recommendation engines. When combined, these tools make our lives more enjoyable, safe, and productive. In a similar spirit, at Altair, we have been working on powering product design and development with AI to make your work lives more enjoyable, and productive. Our focus has been improving processes and outcomes by reducing repetitive, labor-intensive, non-value-added tasks as well as emulating experts and enriching performance predictions with real-time field predictions. What makes these offerings unique is their no-code integration to the tools that you are already familiar with and hence not requiring you to have to leave your own working environment. In this presentation, examples of such AI-Powered product design processes will be demonstrated. The presentation by Dr. Fatma Kocer, VP of Engineering Data Science at Altair, aired at Future.AI in June 2021, and is almost 30 minutes long.

In order to ensure the safety of passengers and on-board personnel, finite element calculation is used at SNCF as part of the acquisition, renovation / modernization projects of trains as a decision aid and preparation for testing approval of trains. This is the main case of the mechanical strength of bolted and screwed assemblies, and more and more of the integration of composite materials into rolling stock structures in order to make them more capacious and less energy intensive. To do this, SNCF is developing methodologies to make the modeling of bolted assemblies and composite parts more reliable, as well as topology optimization. The tools of the HyperWorks suite, and in particular, the OptiStruct solver, allow SNCF to represent its types of materials, as well as these phenomena (bolted assemblies + topology optimization).
