Introduction Optical simulations have become a critical cornerstone in advancing modern photonics, telecommunications, biomedical imaging, and optoelectronic device engineering. Accurately modeling light-matter interactions is essential for optimizing device performance, reducing fabrication costs, and accelerating innovation cycles. In this landscape, COMSOL Multiphysics has emerged as one of the leading platforms, offering sophisticated tools for simulating electromagnetic […]
Challenges or Open Questions While COMSOL Multiphysics 6.3 brings substantial advancements, it does not fully eliminate persistent challenges inherent to high-fidelity multiphysics simulation. One significant hurdle remains the computational demands associated with large-scale or real-time simulations. Even with the inclusion of GPU acceleration, scenarios involving fully coupled nonlinear phenomena across disparate scales often require vast […]
If you’ve ever felt the drag of manual steps slowing down your simulation-prediction pipeline, you’re not alone. Engineers, researchers, and data scientists have long struggled to bridge the gap between physics-based modeling and data-driven analytics. But what if I told you there’s a way to automate this entire process — from simulation to AI prediction […]
Even if different software tools provide necessary methods and technique to generate professional plots since they have to cater a larger audience, they prefer. to add a ton of feature that may be too much for someone who just wants to generate the academic research articles. So that is why I created the tool from […]
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 […]
