⚙️ *COMSOL Multiphysics Tutorial: Natural Frequencies of a Submerged Cantilever Beam in water* 💧

In this COMSOL Multiphysics tutorial, we investigate how immersing a cantilever beam in a fluid, specifically water, affects its natural frequencies. By coupling *Pressure Acoustics* with *Solid Mechanics* we demonstrate the impact of added mass from surrounding media like air and water, and how it lowers the beam’s resonant frequency compared to the vacuum case.

This step-by-step simulation highlights key concepts in acoustic-structure, making it ideal for students, engineers, and researchers in vibration and acoustics.

🔍 *What You’ll Learn:*

✅How to set up a 3D eigenfrequency analysis in COMSOL
✅How to use *acoustic structure interaction* physics
✅The influence of added mass effect on natural frequencies
✅How to identify and interpret acoustic and structural modes
✅Comparative analysis of results in vacuum, air, and water

📌 Whether you're working on vibroacoustics, submerged structures, or just starting with COMSOL FSI simulations, this video will help you build a strong foundation.
