Editing and Repairing Surface Meshes in COMSOL Multiphysics®
Modifying imported meshes can be helpful in certain scenarios, like when you need to move or rotate the mesh, when it has holes or self-intersections, or when you want to intersect it with a plane. In this blog post, I will discuss the functionality for editing and repairing surface meshes that’s available in the COMSOL Multiphysics®…
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.

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…
