Fast multipole BEM
Iterative, low-memory acceleration for large boundary and field problems.
Product overview
Fast boundary element acoustic solvers for low to high frequency problems
FastBEM Acoustics solves large three-dimensional acoustic radiation, scattering, and interior/exterior problems using FMM, ACA, direct BEM, and high-frequency methods.
Why boundary elements
Model the boundary surfaces, not the volumes
FastBEM uses a boundary-only formulation for the three-dimensional Helmholtz equation. This can reduce model preparation and problem size for unbounded exterior acoustics while preserving detailed surface geometry.
Models can include several million degrees of freedom on desktop workstations and larger cases on HPC systems.
