Introduction In modern scientific and engineering workflows, the presentation of simulation results is just as crucial as the simulations themselves. With peer-reviewed journals, academic conferences, and technical presentations demanding high-quality visuals, the ability to export clear, detailed images directly from simulation platforms like COMSOL Multiphysics becomes not just a convenience but a necessity. COMSOL, widely […]
In this tutorial, we will explore how to create and excite a Gaussian pulse in COMSOL Multiphysics—an essential technique used across multiple physics domains including acoustics, electromagnetics, structural dynamics, and heat transfer. The Gaussian pulse is known for its smooth, localized shape, which makes it ideal for studying system responses without introducing artificial high-frequency content […]
Introduction In the realm of multiphysics simulation, geometry is not merely a prerequisite—it is foundational. As the complexities of engineering systems increase and interdisciplinary workflows converge, the ability to construct and manipulate precise geometries within simulation environments like COMSOL Multiphysics has become indispensable. Advanced geometry tools are pivotal not only for enhancing simulation fidelity but […]
Introduction COMSOL for Multiphysics Modeling : Multiphysics modeling represents one of the most transformative methodologies in contemporary engineering and scientific research. By simulating complex interactions between different physical phenomena—such as heat transfer, fluid flow, electromagnetic fields, and structural mechanics—researchers can gain deeper insights into system behavior, accelerate design iterations, and reduce reliance on costly prototypes. […]
Introduction Mesh generation stands as a foundational step in the finite element analysis (FEA) workflow, especially within the COMSOL Multiphysics environment. In essence, meshing discretizes the simulation domain into smaller, finite subregions—termed elements—where the governing equations can be numerically approximated. Despite being preparatory, this step has far-reaching implications for the accuracy, efficiency, and reliability of […]
A PN junction is the fundamental building block of nearly every modern semiconductor device, including diodes, transistors, solar cells, and LEDs. In this blog post, we’ll walk through the key physics behind the PN junction and show how to simulate it in COMSOL Multiphysics using the Semiconductor Module. We’ll also derive relevant equations and compare […]
