Enriched finite elements for time-harmonic Webster’s equation

This work presents an enriched finite element method (FEM) dedicated to the numerical resolution of Webster’s equation in the time-harmonic regime, which models many physical configurations, e.g. wave propagation in acoustic waveguides or vibration of bars with varying cross-section. Building on the...
