Description
The rapid development of computational acoustics has enabled the creation of digital twins for a wide range of engineering applications. Among the most versatile numerical approaches are the Finite Element Method (FEM) and the Boundary Element Method (BEM), both of which are now available in advanced commercial packages supporting full-scale acoustic design and verification.However, innovative research concepts often require transparent and customizable tools that expose the underlying numerical formulation capabilities that commercial software rarely provide. This motivates the use of programmable, open modeling environments that allow researchers to inspect, modify, and extend the core algorithms, particularly in BEM-based scattering analysis.Building on our earlier contribution, this paper presents mm-bem, a lightweight web-browser application implementing a classical BEM formulation for acoustic scattering from mesh-defined objects. The tool runs entirely client-side, requires no installation, and provides interactive visualization of both near- and far-field responses. As a demonstration, we analyze the scattering behaviour of a periodic lattice of spheres, illustrating the applicability of the approach to sonic-crystal configurations.
