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.
Ultrasonic Simulations with COMSOL Multiphysics®
I will describe the application of the COMSOL Multiphysics® software to the simulation of ultrasonic wave emission and propagation. In addition, I will discuss three particular applications, emphasizing the results obtained and the insights gained from simulations.
Three-dimensional eigenmode simulations have been used to predict the dependence of surface wave velocity on the resistivity of sensing overlayers. Simulations have also aided in the understanding of unexpected peaks in the input admittance of surface acoustic wave emitters. Frequency domain simulations have been used to understand the creation of ultrasonic nodes and antinodes in microfluidic channels bonded to a piezoelectric substrate. This is a multiphysics problem that includes the emission of ultrasonic waves by interdigitated transducers on a piezoelectric substrate, coupling of ultrasonic energy in microfluidic channels, and prediction of the trajectories of particles in the channels. In a final example, I will show how transient simulations can be used to gain insight into the propagation of ultrasonic pulses in a complex geometry.
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.
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.
Learn about modeling high-frequency electromagnetic waves using the RF Module, Wave Optics Module, and Ray Optics Module.
Learn to use gradient-based optimization techniques and constraint equations to define and solve problems in shape, parameter, and topology optimization, as well as inverse modeling. The techniques shown are applicable for almost all types of models.
Get a brief overview of using the Structural Mechanics Module and its add-on modules within the COMSOL® software environment.
