- Nonlinear Analysis of Elastomers by Ishant Jain, Raychem RPG Pvt. Ltd.
Hyperelastic materials, such as polymer, are widely used for diverse structural and electrical applications ranging from sealings in cables to heavy load dampers in aviation. The most unique property of hyperelastic materials is the ability to experience large expansion and compression and retain an initial configuration without a considerable permanent set. Cable joints are used to insulate the open part joints of high-voltage and large-capacity power lines, as well as protect against moisture and dust ingress along with mechanical and electrical protection. Cable joint materials consist of multiple layers with the innermost layer having conductive properties, the middle layer with semiconductive properties, and the outer insulating layer. In this research work, a baseline mathematical model has been developed based in the Nonlinear Structural Materials Module, an add-on to COMSOL Multiphysics®, with the help of experimental data available in the form of uniaxial and biaxial stress-strain curves. A least square regression model is fitted with various hyperelastic models such as Mooney–Rivlin, Yeoh, Ogden, and Neo–Hookean, to design the best suitable hyperelastic model for the optimization of material properties and design parameters. The model is used to simulate up to 7x the expansion of a cable joint for calculating the hoop stresses and pressure acting and studying the change in configuration during expansion to design the holdout. The model is further used as a platform for the design and development of heavy duty elastomer springs developed by Raychem RPG and a cable gland shroud to predict their behavior and help in fine-tuning the material properties for best performance.
- Using Modeling and Simulations as a Tool to Gather Critical Insights by R Venkataraghavan, Unilever R&D Bangalore
Modeling and simulations are seen as an alternate approach of inquiry and disparate to the experimentation as a research methodology. However, on the contrary, the best use of these methodologies is in fact in tandem and can often be complementary approaches, filling in for the limitations of either. There is also emerging evidence that in several instances, a "digital first" approach has yielded valuable insights and results for a variety of problems of interest across the design board, work bench, and plant. Specific problems of design and engineering (e.g., product engineering in medical devices) have been well represented, analyzed, and addressed purely from a modeling and simulations approach, before the first material is cut or shaped.
The presentation will make a pitch for promoting modeling and simulations in solving industry-relevant problems, guiding phenomenological understanding, designing products, and engineering safety. The case studies discussed will exemplify the use of modeling and simulations in the context of charge adsorption on electrified interfaces, fluid flow for controlled liquid dosing, and predicting steady-state concentrations in diffusion and convection of a gas.
- Conduction, Convection, and Phase Change with Heat Transfer
In this minicourse, you will learn about modeling conductive, convective heat transfer and about phase change using the COMSOL Multiphysics® software, Heat Transfer Module, CFD Module, and Subsurface Flow Module.
Conductive heat transfer modeling addresses heat transfer in domains and can include heat transfer in thin layers, contact thermal resistance. Convective heat transfer addresses heat transfer due to motion, especially in fluids but also in solids. We will show you how to model natural convection induced by buoyancy forces. We will also discuss how lumped thermal equivalent circuit components can be used for heat transfer analysis, and how they can be coupled to the heat transfer FE models.
Additionally, changes in the temperature of a material can lead to a phase change. This minicourse will present two methods that can be used to model phase change and account for the latent heat of phase change. These two methods, the apparent heat capacity method and the Stefan’s condition, can be used with COMSOL Multiphysics®.

Beyond the single-phase flow capabilities, the Microfluidics Module also allows for two-phase flow simulations to capture surface tension forces, capillary forces, and Marangoni effects. Typical applications include lab-on-a-chip (LOC) devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems.

Finally, the analysis of multiphysics problems in layered shells will be discussed.
- STOP Analysis with the Ray Optics Module
The high-fidelity simulation of optical systems in particularly harsh environments must account for the impact of thermal and structural effects on optical performance. For example, the large temperature changes found in outer space and high-powered laser focusing systems can change the refractive indices due to thermo-optic dispersion. Under extreme conditions, the elements of the optical system may experience significant thermal stress, causing physical deformation and a further degradation of the image quality.
In this minicourse, you will learn how to use the Ray Optics Module to perform coupled structural-thermal-optical performance (STOP) analyses of optical systems. You will learn how to use COMSOL Multiphysics® to compute temperature and displacement fields using the finite element method (FEM) and then couple these fields to a ray optics simulation using built-in optical dispersion models. The distinction between unidirectional and bidirectional couplings in STOP analysis models will also be explained.

In this minicourse, you will get an overview of how to model fluid-structure interaction, thermal stresses and thermoelastic damping, electromechanical forces, magnetostriction, piezoelectricity, poroelasticity, and acoustic-structure interaction. The built-in multiphysics couplings are highlighted, together with examples of how to create your own couplings.

- Panel Discussion: Simulation Apps for Engineering Education: A New Paradigm
Engineering education today is at a crossroads. On the one hand is the challenge of keeping students engaged in class and ensuring they understand basic concepts, while they are inundated with information over the internet. On the other hand, curricula in traditional engineering disciplines are in need of an overhaul as multi-disciplinary engineering has become the need of the day, with an increased focus on the pace of innovation.
It is imperative that new technology be used to handle these new challenges. In the realm of physics- and engineering-based courses, simulation applications are helping to strike such a balance by introducing students to complex concepts in a simplified format. During this session, you will learn how multiphysics models can be developed into specialized applications for teaching, enabling you to create a virtual lab during lecture sessions. Explore how easy-to-use apps enhance classroom learning, helping students visualize theoretical concepts.
Join your peers in a panel discussion where you can see how your colleagues use apps to engage students, accelerating the learning process. The session will also give you an opportunity to know first-hand how students have benefited from apps used in their curriculum.
