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…

Scale-Adaptive Unsteady Turbulent Flow Simulations
The Turbulent Flow, SST interface now supports scale-adaptive simulation (SAS) by incorporating the von Kármán length scale into the turbulence model. This approach resolves a broader range of turbulent scales and provides highly detailed flow fields. SAS can be applied in multiphysics contexts such as fluid–structure interaction, reacting flow, nonisothermal flow, and flow-induced noise, delivering more…
Shooting for the Stars: The History of Astrophotography
It’s no surprise that as soon as we could, people were trying to take photographs of the stars. Nowadays, our expertise in astrophotography has only improved, with image quality getting higher and subjects getting further away. Let’s dive into the history of astrophotography and see just how far we’ve come.
Highlights from the COMSOL Conference 2025 Boston
Engineers, scientists, and researchers from across North America joined us at the COMSOL Conference 2025 Boston to exchange ideas and gain inspiration from the many ways modeling and simulation is being used to drive innovation. Throughout the three-day event, attendees were able to hear keynote talks and invited talks from leaders in industry and academia, learn…
Why ROMs Cannot Completely Replace Multiphysics FEA
When working with complex, compute-intensive simulations, multiphysics events rank high. A faithful recreation of a fluid-structural or thermo-electromechanical interaction using physics solvers and mesh models could keep a team and its hardware occupied for days, jeopardizing timelines and product releases.

Simulating Antenna Crosstalk on an Airplane
As communication systems in aviation become more complex, multiple antennas are often placed on the same airplane. This creates crosstalk, or cosite interference, which occurs between the antennas and can disturb the operation of the aircraft. The Antenna Crosstalk on an Airplane’s Fuselage tutorial model shows that you can simulate the interference between two identical antennas…
Simulation app introduces personalized oncology care
Despite improvements to the current available treatments for breast cancer, determining an accurate prognosis to guide treatment decisions remains a challenge. One approach that could help improve patient care is predictive oncology. This approach is a shift from traditional cancer treatments, instead taking patient-specific data into account in a more precise way so that oncologists can better understand how tumors…
