Multiphysics Modeling in Machine Diagnosis

Subhashish Dasgupta, ABB India Corporate Research Center

Multiphysics simulation can be used for optimizing product design and evaluating new diagnostic methods for industrial machinery. In this session, Dr. Subhashish Dasgupta, senior principal scientist at ABB Corporate Research Center, will discuss the role of the COMSOL Multiphysics® software in an ABB project exploring new diagnostic ideas for rotary machines. He will talk about the proposal of an idea to noninvasively detect and identify specific machine defects through the use of multiple flux sensors around the hydro-generator. Dasgupta will also go over the development of a multiphysics model to simulate the generator and how the simulation led to the identification of defects. Lastly, he will discuss testing the concept on a smaller scale to verify the model findings.

10:55 a.m.

In this session, we will cover the updates in the electromagnetics products.

In version 6.2 of the AC/DC Module, nonlinear motor and transformer simulations have become significantly faster due to a new method for time-dimension periodicity. The module now includes dielectric models for tissue simulation, and dedicated functionality streamlines the modeling of imperfectly stranded conductors, like litz wires. For RF Module and Wave Optics Module users, high-frequency analysis, based on the boundary element method, is enhanced by the introduction of new boundary conditions. The Plasma Module offers more efficient handling of chemical reactions in plasmas and microwave plasma simulations. The Semiconductor Module includes several performance and robustness improvements, enabling users to preview doping profiles before solving.

Digital Validation of E-Powertrain Battery Cooling

Mathusuthanan Sababathy, Renault Nissan Technology & Business Centre India

Recent government regulations and the introduction of electric powertrain vehicles have led to the emergence of many new vehicle manufacturers in the market. This dynamic in the automotive industry has made it necessary for OEMs to shorten their vehicle development time in order to be more competitive. Simulation plays a key role in reducing the upstream development lead time by allowing engineers to validate various components and system designs digitally. To maximize the utilization of simulation, it is necessary to ensure that the digital validation methods used are robust. In this talk, Mathusuthanan Sababathy, CFD Technical Leader at Renault Nissan Technology & Business Centre India, will discuss the robustness of simulation-based thermal validation for batteries.

2:30 p.m.

In this session, we will cover the updates for structural mechanics and acoustics in version 6.2.

Users of the structural mechanics products will see updated damage and fracture modeling capabilities, along with tools for circuit board warpage computation and magnetic–structure multiphysics analysis of electric motors. This version also introduces capabilities for studying transport in solids, which can be used for modeling electromigration and other phenomena. Moisture transport is now more tightly integrated with structural deformations, including how it modifies the storage coefficients and porosity. Inertia relief analysis — now automated in the new version — makes it easier to analyze unconstrained structures that are accelerated by external loads.

This version also introduces a viscoplastic material model specialized for the unique properties of lithium in battery applications. Usability and performance have been significantly enhanced for parameter estimation of experimental data, including uniaxial, biaxial, and cyclic load cases.

For Acoustics Module users, frequency-dependent impedance boundary conditions now enable audio engineers to more accurately simulate acoustics in the time domain with realistic absorption. The Poroelastic Waves feature has been extended to include anisotropic materials, and users will notice considerable performance enhancements in impulse response calculations for room and cabin acoustics simulations using ray acoustics.

3:15 p.m.
Keynote Talk
Mechanical Engineering-Based Decision Support Tools for Cerebral Circulatory Disorders

Prasad Patnaik, Indian Institute of Technology

Continuous supply of blood through our circulatory system can sometimes cause a number of life-threatening circulatory disorders like myocardial infraction and stroke. In this session, Dr. Prasad Patnaik BSV, professor at the Indian Institute of Technology Madras, will focus on CFD analysis tools for solving cerebral circulatory disorders such as stenosis, aneurysms, AVMs, and MMA. He will discuss how the approach typically starts with a simple CT scan, identifying the underlying disease-specific condition through image analysis, and analyzing patient-specific scenarios with the aid of computational simulations. Patnaik will also talk about CFD-backed decision support tools for clinicians for various cerebral circulatory disorders, in particular, intracranial aneurysms.

3:40 p.m.
Tea Break
3:55 p.m.

COMSOL Multiphysics® version 6.2 comes packed with new functionality for fluid flow and heat transfer.

In the CFD Module, large eddy simulation (LES) is implemented for compressible flow for accurate modeling of the flow of gases at Mach numbers below 0.3. There are also seven new Reynolds-averaged Navier–Stokes (RANS) turbulence model interfaces for high-Mach-number flow. A new potential flow interface can be used to get good initial values for the flow and to obtain faster convergence.

In the Heat Transfer Module, the SST turbulence model has been added for accurate nonisothermal flow and conjugate heat transfer simulations. The ASHRAE weather data feature is extended with a search function based on a GPS position, i.e., the feature finds the closest weather station to the GPS position. Additionally, a new thermal connection feature has been added in order to connect and add thermal resistance between two surfaces that are not geometrically in contact in the model.

Join us in this session to learn more about these updates as well as additional fluid flow and heat transfer news!
