Five wind turbines
557,470 boundary elements, half-space Green’s function, 200×200 m ground field, ka=5. Historical case time: 4 minutes.
Application examples
Large acoustic models solved on a laptop workstation
These production-scale examples were run on Windows 11 with an Intel Core i7-13800H laptop. The reported model settings use a convergence tolerance of 1×10−4.
High-frequency head scattering
Head-scattering model evaluated at ka=50, approximately 11 kHz.
Skipjack submarine
250,220 DOF, propeller radiation and incident-wave scattering in a water half-space at ka=383.7.
Engine block
132,764 elements, prescribed surface velocity, and surrounding field evaluation at ka=3.6, or 546 Hz.
Urban propagation
Sound interacting with buildings and barriers
Street block: plane wave
273,870 building elements plus a ground field surface at 200 Hz, ka=366.
Street block: point sources
Three sources along the main street reveal reflection and shielding by the buildings.
