Simulating a Sphere Magnetic Field Earth’s magnetic field is often modeled as a dipole—a conceptually simple yet physically rich approximation. This field arises from complex dynamo processes in Earth’s core but behaves, on large scales, much like the field produced by a uniformly magnetized sphere.In research, this analogy allows us to simulate, visualize, and study […]
Auto-Increment Version and Date Comments in COMSOL Application Builder Have you ever wished COMSOL could automatically track version numbers or update timestamps when working in the Application Builder? If you’re building simulation apps or managing complex models, having a simple built-in versioning system can go a long way in documenting changes — even if it’s […]
Most scientific journals have clear expectations when it comes to figure styling, particularly for plots and graphs. They typically prefer clean, minimal designs with uniform font styles such as Arial, Times New Roman, etc and font sizes that remain clearly legible after reduction—usually no smaller than 8–10 pt. Axis labels and tick marks should be […]
Eddy currents are circulating currents induced within conductors when they experience a changing magnetic field. These currents arise due to electromagnetic induction, following Faraday’s Law, and are opposed by Lenz’s Law, which states that the induced current will flow in a direction that opposes the change causing it. This phenomenon is particularly significant in electrical […]
Thermoelectric modeling involves simulating the direct conversion of heat energy into electrical energy (and vice versa) using numerical methods like Finite Element Analysis (FEA). This approach enables engineers and researchers to design, optimize, and validate thermoelectric devices such as thermoelectric generators (TEGs), Peltier coolers, and energy harvesting systems. FEA helps in solving complex multi-physics interactions […]
Supercapacitors, also known as electrochemical capacitors or ultracapacitors, have gained significant attention due to their ability to store and deliver energy at high power densities. They bridge the gap between conventional capacitors and batteries, offering rapid charge/discharge cycles with long operational lifetimes. To understand and optimize supercapacitors, numerical simulation is crucial. COMSOL Multiphysics provides a […]
