Technical Details:

  • Time-harmonic acoustic wave problems (governed by the Helmholtz equation with a complex wavenumber) in 3-D interior or exterior, and full or half-space/symmetry domains
  • Dual (Burton-Miller) boundary integral equation (BIE) formulation, free from irregular frequencies for exterior domains and well-conditioned for thin structures
  • Advanced adaptive wideband fast multipole, adaptive cross approximation, fast conventional direct BEM solvers, and high-frequency BEM (HFBEM), using parallel computing with OpenMP
  • Boundary conditions (BCs): pressure, particle velocity, and impedance BCs
  • Acoustic sources: multiple plane incident waves, reverberant condition, monopole and dipole point sources, and any other user-defined acoustic sources
  • Complex values of the wavenumbers to introduce damping/attenuation in the acoustic fields
  • Output results: pressure, particle velocity, sound pressure level (SPL), sound intensity level (SIL) on both domain boundary and field surfaces, total sound power and sound power level, acoustic transfer matrix (ATM) or vector, and acoustic panel contribution factors
  • Fast evaluation of solutions on new field surfaces using previously saved results on the boundary for the same BEM model
  • Simple input data structure, easy to integrate with in-house codes and other commercial CAE software
  • Interface with ANSYS® and NASTRAN for building and importing the BEM models
  • Output to Tecplot® for fast post-processing and visualization of the BEM models and results
  • Animation of the BEM results in the time-domain with Tecplot®
  • Java based GUI for fast pre- and post-processing of the BEM results
  • For Windows® XP/Vista/7/8 32-/64-bit OS and Linux 32-/64-bit OS
  • Customized versions can be arranged
