We analyze the modal response of the top plates of archtop guitars using free boundary
conditions. Starting from the three-dimensional scan of a real archtop guitar, we build a
mesh of its top plate using a non-invasive process. Once the mesh of the plate is built, we
compute its vibrational response by finite element method simulations and perform many
different analyses. The outer surface of the mesh matches the scan, while we retain the
freedom to control the shape of the inner surface. This way we can change some of its …
