This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including geometry creation, setting up physics, meshing, solving, and postprocessing.
3D Flow Visualization of an Oscillating Beam
In this presentation, Akshat will demonstrate the use of the COMSOL Multiphysics® software for modeling the flow around an oscillating piezoelectric fan. This model was recently used to show the three-dimensionality of the flow field around an oscillating fan and the work was published in the Journal of Fluids and Structures. The oscillating fan was studied here for application in electronics cooling, but the technique can be extended to the study of flapping bird or unmanned air vehicle (UAV) wings, among other applications. Akshat will discuss the model setup, techniques used to simplify the model, postprocessing methods, and simulation results.
Toward Faster Mixing in a Decimilliliter-Scale Batch Reactor
A three-dimensional, time-dependent diffusion simulation was performed using both isotropic and anisotropic diffusion coefficients to simulate mixing processes where the mixing occurred at the same and different rates, respectively, along orthogonal axes of the container volume. This was used to evaluate the performance of a mixing metric and imaging setup and to inform an experimental design. To evaluate the suitability of various methods of excitation at facilitating mixing, a two-dimensional simulation was performed. This simulation, based on the Acoustic Streaming in a Microchannel Cross Section model, contained two solver steps. In the first step, the first-order acoustic field for a given excitation was solved for in the frequency domain. This field was then used to determine the second-order acoustic streaming volume force, which was used as an input for a time-domain stationary solution for the velocity field using the Laminar Flow interface (Navier-Stokes equations). Results from both sets of simulations will be presented and compared to experimental data.
Learn how to convert a model into a custom app using the Application Builder, which is included in the COMSOL Multiphysics® software. You can upload your apps to a COMSOL Server™ installation to access and run the apps from anywhere within your organization.
This minicourse will provide an introduction to modeling fluid-structure interaction (FSI) using the COMSOL Multiphysics® software. It will explore the different classifications of FSI analyses and discuss which tools within COMSOL Multiphysics® can be used to solve each case. This covers coupling CFD with structural mechanics as well as coupling acoustics with structural mechanics. During the minicourse, a modeling example of FSI in a network of blood vessels will be presented as a live demo.
Learn about modeling high-frequency electromagnetic waves using the RF Module, Wave Optics Module, and Ray Optics Module.
Learn about the meshing tools provided in the COMSOL Multiphysics® software. We will introduce you to basic meshing concepts, such as how to plot the mesh or tweak the meshing parameters, as well as advanced topics such as swept and mapped meshes.
The design and modeling of microelectromechanical systems (MEMS) is a unique engineering discipline. Learn how to model MEMS sensors and actuators based on smart materials for a wide range of applications, including vibration and active shape control as well as structural health monitoring and energy harvesting. This minicourse will also present the electric circuit functionality of the COMSOL Multiphysics® software and discuss how electric circuit models can be coupled to finite element models within the context of MEMS applications.
Partial differential equations (PDEs) constitute the mathematical foundation to describe the laws of physics. This minicourse will introduce you to the techniques for constructing your own linear or nonlinear PDE systems in COMSOL Multiphysics® and will also include how to add ordinary differential equations (ODEs) and algebraic equations to your models to include advanced functionality in your simulations, such as PID control.
When presenting your results, the quality of your postprocessing will determine the impact of your presentation. This minicourse will explore the many tools in the Results node designed to make your data look its best. These include mirroring, revolving symmetric data, cut planes, cut lines, exporting data, joining or comparing multiple data sets, as well as animations.
