Modeling of Excitations with the Magnetic Field Formulation

When using the AC/DC Module, an add-on to the COMSOL Multiphysics® software, there are five interfaces within which we can model time-varying magnetic fields and inductive effects. Each solves a different form of Maxwell’s equations and has different modeling benefits. Here, we will look in depth at one of these interfaces, the Magnetic Field Formulation (MFH)…

Modeling Surface Acoustic Wave-Induced Streaming in a Droplet

Surface acoustic waves are capable of generating a streaming flow inside a droplet, enabling contactless mixing — a useful application in the area of microfluidics. Due to the multiphysics nature of the droplet streaming, a numerical study often makes several assumptions to capture only a part of the phenomenon. In this blog post, we will get…

Surrogate Models for Faster Simulations and Apps

The COMSOL Multiphysics® software includes functionality for creating and using data-driven surrogate models, which are simplified, computationally efficient models that approximate the behavior of more complex and often more expensive simulations. Thanks to their relative simplicity, surrogate models have many practical uses, such as enhancing app interactivity and accelerating optimization and uncertainty quantification tasks.

Sonos Optimizes MEMS Microphone Design to Reduce Distortion from Wind Noise

MEMS microphones can be found in a wide variety of consumer products, including cellphones, laptops, and smartwatches. While these bite-sized acoustic sensors are able to process sound sources that vary greatly in tone, timbre, and application, distortion caused by wind noise has proven to be a design challenge since the beginning of this technology’s development.

Modeling a Cellphone Drop Test with Explicit Structural Dynamics

When not being held, our cellphones are rarely more than an arm’s reach away. With so much handling, dropping them is a common occurrence. According to a survey by Allstate, around 78 million Americans reported damaging their cellphones in 2023, with cracked screens accounting for 67% of that damage (Ref. 1). Your phone may be unscathed…

Faster Simulation with NVIDIA GPU Support for COMSOL Multiphysics®

Modeling and simulation has become a cornerstone of science and engineering, providing a framework for describing the physical behavior that influences the operation of devices and processes — from the design of smartphones to the control of nuclear power plants. Such behavior may involve electromagnetic fields, fluid flow, heat transfer, and mechanical stresses, to name a…

Using Acoustic Ray Tracing and GPU in Automotive Applications

Both luxury and standard automakers compete to attract customers with state-of-the art features. Manufacturers often advertise top-notch sound and speaker systems and convenience features, such as parking sensors, to entice customers to choose the highest trim model. The COMSOL Multiphysics® software offers a way to help develop and optimize these features through acoustic ray tracing, which…
