COMSOL Day Canada

Hosted together with CMC Microsystems

Join us and your colleagues from both industry and academia for this 1-day event to learn about how multiphysics simulation is used for all types of engineering applications.

We are hosting this COMSOL Day together with CMC Microsystems, an organization we are proud to collaborate with that provides access to the COMSOL Multiphysics® modeling software for its member university departments and researchers throughout Canada. During the event, we will focus on modeling techniques in COMSOL Multiphysics® for the coupled systems prevalent in MEMS-based sensors, actuators, and filters, as well as optical, microacoustic, and piezoelectric devices. Keynote speakers from industry will provide their perspective on the importance of simulation in multiphysics applications.

COMSOL Day Canada is open for all to attend, whether you are a user of the COMSOL Multiphysics® software or not, and whether you come from academia or the commercial world.

Schedule

10:00 a.m.

To start, we will briefly discuss the format of the day and go over the logistics for using GoToWebinar.

10:05 a.m.

The Application Builder is included in the COMSOL Multiphysics® software and allows you to transform your models into simulation apps controlled by interfaces appropriate for what is being simulated. This type of tool is unique to COMSOL Multiphysics® and will open up the world of simulation to all engineers, operators of processes, and scientists. This session will demonstrate the use of the Application Builder and how it can fundamentally augment how your organization approaches simulation.

10:30 a.m.
Parallel Sessions
Sensors, Actuators, and Filters

Sensors, actuators, and filters are MEMS devices used in a variety of areas. The design of these devices requires deep knowledge of all physical processes involved as well as the environment in which they operate. This session will demonstrate modeling techniques for accurate modeling of MEMS devices.

Batteries and Electrochemistry

Batteries are a key component in the power storage and utilization in a variety of mobile and stationary devices and equipment. Battery modeling is based on the fundamentals of electrochemistry and requires a simulation tool that can combine these phenomena with many other physics such as electric current flow, fluid dynamics, and heat transfer. This session will touch on the capabilities and specific add-on modules for different electrochemistry-based applications found within the COMSOL® product suite.

11:15 a.m.
Parallel Sessions
Microscale High-Frequency Devices

The simulation of Maxwell's equations in the high-frequency electromagnetic wave regime is essential in designing devices based on RF and microwave transmission, as well as optical properties. This session will discuss the modeling of such applications when applied to devices in the microscale.

Optimization

In the manufacture of MEMS and similar devices, it is imperative to optimize their design and operating conditions. During this session, we will demonstrate how optimization can be applied to your COMSOL Multiphysics® simulations using the Optimization Module. You will receive an overview of large-scale optimization modeling in the COMSOL® software and techniques to accelerate your progress. You will also get a demonstration of gradient-based optimization techniques and constraint equations to define and solve problems in shape, parameter, and topology optimization.

12:00 p.m.

Designing a MEMS Acoustic Flow Microphone

Commercial microphones rely on sensing pressure to detect sound. However, most animals rely on sensing airflow instead, due to the advantages it offers regarding the detection of the direction of sound. We will look at how the Thermoviscous Acoustics and Electrostatics Boundary Element features in COMSOL Multiphysics® are helping Soundskrit, the Montreal-based startup I am a part of, design a MEMS acoustic flow microphone.

12:30 p.m.
Break for Lunch
1:00 p.m.

CMC Microsystems: Lowering Barriers to Technology Adoption

During this talk, Owain Jones will describe how CMC is making COMSOL Multiphysics® and complementary products and services available to the research community in Canada and how attendees can access COMSOL licenses and related infrastructure.

1:15 p.m.

COMSOL Multiphysics® for Applied Magnetics Modeling

In this presentation, we will review the use of COMSOL Multiphysics® to model systems in the general field of applied magnetics. Recent work involves using COMSOL Multiphysics® for the modeling and optimization of a range of systems, including pulsed eddy current (PEC) inspection systems for nondestructive evaluation (NDE), linear induction motors (LIMs) for applications in Hyperloop systems, and the electrical breakdown of gases and magnetic confinement of the resulting plasma with applications in nuclear fusion. This presentation will focus on the latter application.

1:45 p.m.
Parallel Sessions
Acoustics

Acoustic pressure waves in fluids such as air or water interact with surrounding structures resulting in vibrations in solids and absorption in porous materials. Furthermore, in narrow and microstructures, thermal and viscous losses in the fluid become significant and need to be included in any modeling analysis. In this session, we will demonstrate the features of the Acoustics Module to illustrate the simulation of these waves, subsequent losses, and their effects.

Microfluidics

Modeling flow in the microscale has to take into account properties that scale differently at these smaller length scales. Diffusion, particle flow, multiphase flow, fluid-structure interaction, and electrokinetic effects inherently require explicit techniques to take into account their contribution to the microfluidics application at hand. This session will touch on these multiphysics phenomena and how they are resolved in microdevices.

2:30 p.m.

This session will introduce new users of COMSOL Multiphysics® to its capabilities and the fundamental modeling workflow for modeling single-physics and multiphysics applications. It will demonstrate the process of building and running a model based on a practical example. It will also exemplify how such a model can be reformatted into specialized applications that any nonexpert in simulation can use. Join this session to see how COMSOL Multiphysics® can transform your simulation and modeling requirements.

3:15 p.m.
