How it works:\n* Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh.\n* Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles.\n* Sound model factors in strike location, Rayleigh damping, and mallet width.\n* Includes Kac drums I & II to demonstrate identical sound spectra from different geometries.\n* No frameworks, build steps, or dependencies.

Repo and tests: https://github.com/BaselAshraf81/eigendrum

Happy to answer any questions about the FEM solver or Web Audio setup!
