Concept design is a crucial stage in the product development life cycle of automobiles, involving an iterative collaboration between the design and computer-aided engineering (CAE) teams. The CAE analysts work hard toward evaluating design options to meet the system performance and weight targets for a vehicle. For their suggestions to be incorporated in the final design, however, the results need to be available well before the design is finalized, which is often not the case; this increases the product development cycle time. Therefore, it is important to evaluate more design options at the concept phase itself for a robust and optimized vehicle architecture that meets the predefined targets. Simulation software like COMSOL Multiphysics® enables design engineers to quickly test various designs while allowing CAE engineers to focus on detailed CAE analysis, such as multidisciplinary optimization for improving performance and reducing weight.

Leaky SAW resonators are the building blocks of low-loss miniature acoustic filters, which are extensively used in today’s wireless communication circuits. The geometry of these resonators, including metallization thickness and acoustic aperture, plays an important role in determining the performance of these resonators and hence also that of the filter they are a part of. Spurious resonant responses attributed to transverse modes and surface-skimming bulk waves (SSBWs) can substantially corrupt the overall filter response and must be analyzed thoroughly. Multiphysics simulations can be fruitfully utilized to gain insight into the origin of these spurious modes, and the geometry of the resonators can consequently be modified to minimize the modes' effect. This presentation analyzes leaky SAW resonators fabricated on a 42° YX lithium tantalate substrate through simulations in the COMSOL Multiphysics® software. Based on the simulation results, suitable modifications are made to the resonator geometry to improve resonator performance. Finally, results of the simulation are validated against on-wafer tests carried out on fabricated resonators.

- Panel Discussion: Enhancing Classroom Learning with Simulation Tools
Enhancing Classroom Learning with Simulation Tools
One of the most challenging aspects of teaching is to keep students engaged while accelerating their learning process. Students often face difficulties in conceptualizing engineering problems and struggle to understand complex physical phenomena if they cannot be visualized. Traditional experiments can aid learning, but some experiments are expensive and have difficult and time-consuming setup procedures. Simulation tools can close this gap by helping students better visualize multiphysics problems, easily grasp theoretical concepts, and apply their learning in real-life situations.
In this discussion, we will delve into how simulation tools contribute to helping students develop an intuitive understanding of engineering problems and allowing them to explore new ideas and designs.
- Panel Discussion: Maximizing Product Development Efficiency with Simulation Apps
Maximizing Product Development Efficiency with Simulation Apps
Product development is a time-sensitive process that requires the most accurate and comprehensive simulation tools to stay ahead of the competition. Simulation plays a crucial role in the product development life cycle, reducing the dependence on prototyping, which in turn reduces the time to market for any product. Next-generation simulation tools go a step further, bringing the power of simulation to design engineers through custom user interfaces called apps. These apps can be deployed across organizations, enabling other teams to analyze and optimize product designs without the constant involvement of simulation experts.
In this discussion, we will examine the current role of simulation apps in product development and how organizations envision the future of apps within the industry.

During this session, we will focus on the features for modeling surface-to-surface radiation for gray surfaces or multiple spectral bands, such as solar and infrared radiation. We will discuss different examples in order to help identify cases where thermal radiation has to be accounted for.
Defining ambient conditions is a key point in the model definition, especially when solar radiation is accounted for, but there are also other cases. We will review the different means to define the ambient condition and how use them for conduction, convection, and radiation in heat transfer models.

It is the age of data. In every field, data is being used to build predictive models. Will the science of physics simulations get supplanted by this trend? After all, a "simulation" is a predictive model of the behavior of physical objects. Can data modeling/machine learning/A.I. replace simulation technology in these goals?
In this keynote address, Udayan Kanade, CEO of Noumenon Multiphysics, will argue that the final outcome is likely to be more complex than these questions seem to indicate. Rather than being locked in an eternal battle for supremacy, data science and physics simulations will learn to form a novel symbiosis that relies on the diverse strengths of each field. What will this novel symbiosis look like? What changes will each field have to undergo before they can merge? What will the simulation and data science tools of the future look like? And what will the eventual benefit to engineers and to mankind be?

Power cables are of great importance in power transmission and distribution systems. High-voltage cables are used for both AC and DC high-voltage power transmission throughout the world. Technological advances, particularly those relating to materials, have meant that cables can reliably be utilized at ever-increasing voltages and for a broader range of applications and installation conditions than ever before. Accurate determination of cable ratings is important for providing an economical, functional, and safe electrical design. There are two main cable technologies that are commercially available at the moment: mass-impregnated (MI) cables and extruded cables. The relevant physics for MI and extruded cables are quite different. In MI cables, the fluid dynamics and the formation of voids in the insulation during cooling is the main phenomenon that needs to be controlled. The fluid dynamics coupled with electrical conduction governs the partial discharge (PD), which is the limiting factor in the design of MI cables. On the other hand, in extruded cables, the physics behind conduction; interpretation of measurements; understanding of conduction; and, finally, relevant and reliable quality assurance techniques are the main areas of concern. In addition, control of the electric field at the interface between cable and accessories is also a challenge. This demands the implementation of relevant theoretical models to understand the performance of a high-voltage cable system under various stresses (thermal, electrical, and mechanical). The COMSOL Multiphysics® software was used for implementing high-voltage cable models to study the coupled electrothermal or electrothermal and mechanical simulations. In this talk, the role of multiphysics simulations to understand the critical issues in the development of an HVDC cable system is discussed.

In recent years, technological disruptions have resulted in multifold growth in the automobile sector. Studies show that similar kinds of disruptions are expected in the near future as well. Further regulatory changes like Bharat Stage VI (BS VI) and the electrification of conventional internal combustion engine vehicles are also on the verge of implementation. Major challenges faced for BS VI and electric vehicles are their stringent norms and light weight with improved performance. Further, auto original equipment manufacturers (OEMs) are looking at their suppliers as development partners. This has imparted more design responsibilities on the shoulders of the supplier. These responsibilities can be handled swiftly by incorporating computer-aided engineering (CAE) into their new product development (NPD) process. As a result, more and more auto component companies are implementing CAE as a part of their NPD process. Here, the CAE platform/solver selected is of immense importance. Being a multiphysics simulation software, COMSOL Multiphysics® can play a major role in building up products with first-time-right design. Different physics can be combined together and can be analyzed in one place. An example of disc brake thermal prediction is discussed, where different physics are combined to address the brake phenomenon.
