Element's Data
There are a simple duct and just laminar flow, Is it possible to extract the velocity of each element at outlet boundary in Time-dependent study at output times without using "excel", I mean using internal COMSOL's functions? Read more »

Different S11 values for the same frequency
Hi all, I simulate a pin-fed patch antenna at 3.5 GHz. When I set Frequency to **3.5\[GHz]**, The S11 value is -28.474 dB. But if I enter **range(3.3\[GHz],0.1\[GHz],3.7\[GHz])** phrase into the frequencies text box. I get... Read more »

Computing transmittance and reflectance of glass for different wavelengths
Hello everyone, I'm a beginner user of COMSOL, and I'm stuck on a little problem. I'm using the "*Electromagnetic Waves, Frequency Domain*" interface to model an incident wave on a smooth surface, in order to calculate the... Read more »

Unexpected behaviour of "intop" function
Hi all! First of all I'd like to thank this forum, here I have found many answers I needed before. But now I couldn't find any at all. Thing is, I have a quite complicated 2D model of a superconducting magnet. My model... Read more »

Understanding the Drug Reaction Kinetics of Nerve Guides via Modeling
Have you ever pinched a nerve? It can feel like getting struck by a small lightning bolt, but thankfully, the pain often tends to fade within a few days. Those who... Read more »
Electrode Balancing of a Lithium-Ion Battery with COMSOL®
If the electrode balancing for a lithium-ion battery isn't right, the cell open-circuit voltage will never be accurate. In this blog post, we introduce electrode... Read more »
Evaluating the Impact of Bearing Misalignment on Rotor Vibration
Bearings are one of the oldest inventions in the world, and one of the most common. Often, these parts are found in rotating machinery, helping to support other... Read more »
How to Use Circular Ports in the RF Module
The Port boundary condition in the RF Module, an add-on to the COMSOL Multiphysics® software, can be used to launch and absorb electromagnetic energy. We explain how... Read more »
Speeding Up DNA Separation in a Microchannel via Simulation
