One gong of a Philippine Kulintang gong chime. The geometric model based on a 3D surface scan is utilized for finite element method (FEM) physical modelling. Modal deflection shapes ([0,1], [1,1] and [2,1]) obtained from an eigenvalue analysis with free-free boundary conditions. The original instrument is situated at the University of Hamburg, Germany
