Why Fast Multipole Acoustic BEM?

Coustyx is a software for computing Sound Fields. Coustyx integrates Advanced Boundary Element (BEM) formulations with Fast Multipole Method (FMM) to yield fast, accurate solutions to very large problems in acoustics, across a wide frequency range.

Benefits

Large Models:
Integration of BEM with FMM allows Coustyx to handle very large problems (>1 million DOFs) across a wide frequency range without running into memory issues.
Accurate Solutions:
Sound fields computed by Coustyx are extremely accurate. Coustyx solutions are validated extensively with theory and experiment.
Wide Variety of Applications:
Coustyx can solve a wide class of problems from personalized 3D audio (HRTF), designing musical instruments, to tuning muffler systems.

Featured Capabilities

Mesh/Data Interfaces to CAE Software

Coustyx can import mesh and vibration data from several CAE software; Simcenter OptiStruct®, Nastran (.bdf, .op2), Abaqus (.odb), Ansys, and universal file formats.

Robust BEM Formulations

BEM formulations include Helmholtz Integral Equation Collocation, Burton Miller Variational, and Indirect Variational Formulations to address a wide class of problems.

Wide Selection of Boundary Conditions

A number of boundary condition options are available to model all real life situations: specified velocity, pressure, impedance, transfer matrices, discontinuous, perforated plate, etc.

Real World Applications
