This section provides a product outline of WAON, and introduces its features, functions, and operating environment.
"WAON, developed and sold by CYBERNET, is acoustic-analysis software applying the boundary element method (BEM). By using FMBEM, solver applying fast multipole algorithm (FMA) to 3D BEM, analysis time has been dramatically shortened and the memory size has been reduced compared to conventional BEM. "
|Conventional method||parallel processing with 64-bit system using eight CPUs|
|WAON||Single process on the 32-bit Windows system|
WAON is able to selectively use two types of formularizations: Basic Form: BF and Double Layer Form: DLF. This helps resolve problems with various shapes appropriately.
When dealing with external problems of a model without an opening, for example, the matrix differs at around acoustic natural frequencies unique to sound in internal spaces of the model, disabling the analysis to be carried out correctly (apparent eigenvalue problem). To solve such problems, WAON is able to set the number of degrees of freedom at both the front and back of the elements using DLF, and apply characteristic impedance to the whole surface connecting to the internal space, thus allowing elimination of the specificity.
