Learn how to effectively model batteries and battery packs using COMSOL Multiphysics^®. In this minicourse, we will discuss the detailed electrochemistry approach and lumped model approaches to modeling batteries. With the help of the COMSOL Multiphysics^® software, we will also demonstrate how modeling can be used for charge and discharge analysis, abuse modeling, and the thermal management of battery systems.

This minicourse will cover the rich physics involved in structural analysis and acoustics as well as the interactions between them. Interactive examples include transducers, speakers, microphones, SAW filters, smartphones, medical sensors, and many others. We will discuss the range of material models (linear and nonlinear) you can choose from; loading and support conditions; and linking between solids, shells, plates, and beams.

In this guided, hands-on session, we will walk you through an example of modeling fluid flow and give a quick overview of using the CFD Module for laminar, turbulent, and high Mach number flow; non-Newtonian, multiphase, and nonisothermal flows; and flow in mixers. Learn how to accurately model thermal characteristics of systems that include heat transfer by conduction, convection, and radiation. We will review how you can model and optimize systems that include phase change, bioheating, electronic cooling, thermally induced stresses, and thin thermal barriers.

This session will discuss the details of modeling electric machines and high-voltage transmission devices using the COMSOL Multiphysics^® software, along with various multiphysics aspects. We will focus on modeling electric and magnetic fields and on how to capture nonlinearity in magnetic materials. During this session, we will also explain how to model different types of transformers and electric motors, such as induction motors, permanent magnet motors, linear variable differential transformers (LVDTs), generators, alternators, magnetic gears, bearings, and more. In addition, we will discuss how to compute winding and core losses for thermal analysis in motors and transformers. See how electromagnetic forces can be coupled with structural mechanics and acoustics to predict noise in electric machinery.
