Fast, Accurate, Easy to Use, and Cost Effective!

  • Advanced acoustic simulation software based on the boundary element method (BEM) accelerated by the fast multipole (FMM), adaptive cross approximation (ACA), and highly optimized direct solvers.
  • Fast and accurate wideband acoustic analysis from low to high frequencies without compromising the BEM model size and accuracy.
  • Large-scale acoustic BEM models with unknowns (DOFs) up to several millions solved on PCs and even larger models on supercomputers.
  • Predicting sound fields from machines, automobiles, aircrafts, electronic devices, underwater structures, audio equipment, interiors of buildings, environment, and many others.
