Understanding the Drug Reaction Kinetics of Nerve Guides via Modeling
Ever had a pinched nerve? Nerve guides repair this type of damaged nerve cell tissue. To design safe and reliable nerve guides, we can use simulation to understand their drug reaction kinetics.
Electrode Balancing of a Lithium-Ion Battery with COMSOL®
Electrode balancing is an important consideration for battery cell engineers. Get an overview and mathematical framework of this phenomenon and learn how to analyze it in a lithium-ion battery.
Evaluating the Impact of Bearing Misalignment on Rotor Vibration
Bearings are found in devices ranging from MEMS and turbines to electric motors and even ships. How we account for a bearing’s misalignment (and the resulting rotor vibration) depends on its use.
How to Use Circular Ports in the RF Module
Degeneracy in circular ports leads to uncertainty in the mode field orientation. Not so with the Circular Port Reference Axis feature, which lets you define field orientations on port boundaries.
