Maximum value from each slice of cut planes
Hi, I'm simulating air flow through a tube and looking at difference in presure along the system. I want to graph the maximum pressure along different areas of the system. To do this, I would like to find the maximum value of... Read more »

Different results are strange with same definitions but different physics in rmm&mf
Dear all, I am simulating a pm_motor that I defined the magnets with Ampere Law. I used the same value of Remenant flux density. When I reached the result, the result in magnetic field is normal but in rmm field is zero. The... Read more »

Difference between contact pair and identify pair
I am a little confused about the difference between contact pair and identity pair when I do some simulatation of solid machanics . And are there any restrictions of the study type? When we do stationary study, what is the... 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 »
