Webinar “Introduction to the Boundary Element Method in Acoustics”, Prof Simon Chandler-Wilde, University of Reading
For many acoustics applications it is possible to reduce the Helmholtz equation, that governs time harmonic propagation and scattering of acoustics waves in a fluid region, to an integral equation that holds on all or part of the boundary, which can be solved by finite element technology. This method of proceeding is the Boundary Element Method and is attractive in comparison with other full wave solvers for many applications because only the boundary (or some part of the boundary) needs to be discretised, rather than the whole fluid region. In this introduction we explain how this procedure works, talk through when it is effective as a computational method, show some example simulations, and give some indication of areas of current research.
