FeVAcS: A package for visualizing acoustic scattering from 1D periodic obstacles

Abstract

FeVAcS is an open-source finite element software specializing in one dimensional periodic acoustic analyses with scattering obstacles. Leveraging FEniCS Project’s computational capabilities, it solves the Helmholtz equation variational form. This tool simplifies mesh generation, enhances acoustic visualization, and enables easy parameter manipulation for obstacle and domain geometries, along with wave property adjustments. Featuring a user-friendly browser interface, FeVAcS improves accessibility and result sharing. It serves as a vital tool for understanding complexities within exterior acoustic analyses.
