Minicourses

Our most popular event at the COMSOL Conference is the offering of hands-on minicourses. We hold general introductory sessions as well as specialized minicourses to help you delve deeper into your specific areas of interest.




AC/DC

Explore the capabilities of the AC/DC Module for simulation of static and low frequency electromagnetics. This minicourse will focus on modeling resistive, capacitive and inductive devices. We will explore options to create high definition models of such devices to visualize the spatial distribution of electric and magnetic fields. We will also demonstrate techniques to extract lumped parameters such as resistance, capacitance, inductance and impedance from the device models. New features in the software will be showcased as well.

Acoustics & Vibrations

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 structures, thermal and viscous loss in the fluid become significant and need to be included. This minicourse uses the Acoustics Module to demonstrate the simulation of these waves and their effects. Recent news and additions to the module are also presented. Application areas include, but are not limited to: muffler design, mobile devices, transducer design, loudspeakers, pipe acoustics, sound insulation materials, acoustic scattering, transmission, and radiation phenomena.

The Application Builder, included in COMSOL Multiphysics, is a development environment for designing applications based on COMSOL Multiphysics models. You will be able to make COMSOL applications available to your colleagues and customers who are not COMSOL Multiphysics users by letting them connect to COMSOL Server.

Starting with space-independent models, we investigate kinetics using different chemistries, under the controlled conditions typical for laboratory scale and bench scale. To simulate realistic operating conditions, we include the spatial variations in temperature due to convection, conduction and radiation, and in species composition due to convection, diffusion and electromigration. Mixture models, surface reaction and porous media transport will also be discussed.

Electrochemistry, Corrosion, and Electrodeposition

This minicourse covers the Electrochemistry, Corrosion, and Electrodeposition Modules, featuring tailored interfaces to study primary, secondary and tertiary current density distributions in electrochemical cells. Physics effects such as heat transfer, fluid flow and electrochemical reactions can be easily added to a model and is an essential capability of COMSOL Multiphysics.

Equation Based Modeling

Partial differential equations (PDEs) constitute the mathematical foundation to describe the laws of nature. This minicourse provides an introduction to the techniques for constructing your own linear or nonlinear PDE systems. You will also learn how to add ordinary differential equations and algebraic equations to your model.

Fluid-Solid Interactions

COMSOL Multiphysics can perform truly bidirectional fluid-structure interactions where viscous and pressure forces act on an elastic structure and structural velocity forces act back on the fluid. This tutorial presents the ready-made physics interface for this important multiphysics application.

Geometry Modeling and CAD Import

Whether you choose to construct a geometry in the COMSOL Desktop or to import it from a CAD file, this minicourse will demonstrate some useful tools. Did you know that COMSOL Multiphysics can automatically generate the cross-section of a solid object, and that you can use it for a 2D simulation? Or that you can directly import topographic data to create 3D objects? The same tool that you can use to create fluid regions for imported designs can also be used for replacing missing faces in geometric objects. Attend this minicourse to see a demonstration of these techniques and more.

Heat Transfer

Heat transfer enters just about all multiphysics simulations. This minicourse will explore all three forms of heat transfer: conduction, convection and thermal radiation. We will explore both forced and natural convection and the predefined fluid-thermal couplings. Additional topics are temperature dependent material properties and using library correlations for heat transfer coefficients.

Introduction to COMSOL Multiphysics

This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics modeling environment. All of the key modeling steps including geometry creation, setting up physics, meshing, solving, and postprocessing will be addressed. This general introduction is a great way to get up to speed prior to attending the specialized minicourses.

LiveLink for  MATLAB®

This minicourse focuses on how to interface MATLAB® and COMSOL Multiphysics. Learn how to use MATLAB® as a scripting interface to implement and solve your COMSOL Multiphysics simulation, export or import your data at the MATLAB® command prompt, and define model properties such as boundary conditions or material definitions within an m-function.

MEMS

The simulation of microelectromechanical systems naturally requires a multiphysics approach. Especially important is the accurate application of the electrical boundary conditions and forces on mechanical structures.
