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 Simulation accuracy and robustness are foundational to any computational modeling platform, and COMSOL Multiphysics—widely used by engineers, researchers, and physicists for simulating complex coupled systems—is no exception. As the complexity of a model increases, so does the likelihood of encountering solver errors, memory issues, and stability problems. For technical professionals, effectively identifying and resolving […]
