🎶Eigendrum Solves Drumhead Modes With Finite Elements
Solve drum vibrations like a pro with math
TL;DR
Eigendrum uses finite element methods to solve the eigenvalue problem of drumhead vibrations. It's not just about shapes; it's about understanding physics and mathematics behind sound.
Eigendrum lets you explore how different drum shapes affect their vibration modes, using finite element analysis. If you're into acoustics or math, this is a neat way to see the physics in action. The site uses exact solutions for testing, ensuring accuracy within a tenth of a percent.

Key Points
Eigenvalue problem solved using conforming finite element methods
Meshes shapes into triangles for accurate stiffness and mass matrix calculations
Exact solutions tested on every change to ensure accuracy within ±0.1%
Rayleigh damping applied, with loss rising as the square of frequency
Two identical spectra drum shapes built in 1992 by Gordon et al.
Why It Matters
