Multiphysical Analyses in Modern Research and Development

Modern industrial design requires advanced simulations covering a wide spectrum of scientific disciplines. One of the most important analysis types are multiphysics simulations, where different research areas are coupled. In the talk, the industrial approach and the implementation of the COMSOL® software for multiphysics simulations are presented.

10:00

Application of COMSOL Multiphysics® for Modeling of Streaming Electrification Processes

A numerical model implemented in the COMSOL Multiphysics® simulation environment will be presented, which allows for investigation of processes related to streaming electrification. The streaming electrification process is based on accumulation of electrical charges in a certain area of a tank filled with liquid dielectric (transformer oil) as a result of its flow. Transient time simulations are performed as part of the study, while the object is constructed in 2D axisymmetric geometry. Simulations refer to the analysis of oscillatory movement. The model takes into account laminar or turbulent flow depending on the motion parameters and the transport of the diluted particles. In the research work, the distribution of electrification currents is analyzed for various model parameters, including the speed and frequency of fluid flow and the diffusivity of the liquid dielectric.

Acoustic Structure Design Using COMSOL Multiphysics®

Building acoustics is a dynamically developing branch, driven by growing users' requirements. A bunch of theoretical relations, which have been used heretofore, let acousticians roughly estimate the parameters of plain structures. Using FEM, it is also possible to obtain more accurate results for constructions with complicated geometries.

In this presentation, some possibilities of COMSOL Multiphysics® in acoustic structure modeling will be shown. Also, different ways of acoustic insulation modeling will be compared with results obtained in laboratory measurements.

14:00

Multiphysics Modeling of Sound Absorption in Porous and Fibrous Media

Sound absorption in porous and fibrous materials depends strongly on their microstructure. There are well-developed models that relate sound propagation to several transport parameters of porous microgeometry. These parameters can be calculated, provided that a (periodic) representation of the microgeometry is available. Such representations can be constructed directly in the COMSOL Multiphysics® software or they can be imported using the add-on CAD Import Module if they are externally built; e.g., from computed tomography scans. Then, three uncoupled problems (a viscous flow, a heat transfer, and an electric conduction problem) — also involving some periodic boundary conditions (a feature available in COMSOL Multiphysics®) — can be solved on the periodic fluid domain of a porous or fibrous medium in order to determine the transport parameters from the microscale level. Finally, these parameters serve on the macroscale level — where the Acoustics Module, an add-on product to COMSOL Multiphysics®, can be used — to estimate the overall sound propagation and absorption. The presentation illustrates this approach for an open-cell foam and a fibrous material.

COMSOL on Workstations, Servers, and Clouds – What’s the better system, when?

Are you working with CAE software? Then you might have experienced from time to time that your workstation or your server is overloaded, or it is simply too slow to perform your CAE simulation within a reasonable time and with the necessary high accuracy. According to a study of the US Council of Competitiveness 57% of all CAE engineers are experiencing this bottleneck during their product design and development simulations. And this is one of the reasons why in recent years engineers are showing a growing interest in complementing their in-house computing with the additional use of cloud computing for their CAE more complex and compute-intensive simulations.

This presentation compares the benefits and challenges of using workstations, servers, and cloud resources for CAE simulations based on COMSOL Multiphysics® and COMSOL ServerTM, for small and medium size businesses as well as for global corporations. It also includes a comparison of the Total Cost of Ownership (TCO) of in-house servers and public cloud resources. Novel software technologies are presented which remove most of the previous roadblocks of cloud computing, such as security challenges, conservative licensing models, slow data transfer, and losing control over your assets in the cloud.

15:00
Coffee Break
15:30

Get an introduction to the techniques for constructing your own linear or nonlinear systems of partial differential equations (PDEs), ordinary differential equations (ODEs), and algebraic equations within the COMSOL Multiphysics® software.

16:00

Explore the capabilities of COMSOL Multiphysics® for electromagnetics in the static and low-frequency regime with a focus on the AC/DC Module. Learn also about modeling high-frequency electromagnetic waves using the RF Module, Wave Optics Module, and Ray Optics Module.
