BEAT is a boundary element method (BEM) based program for the acoustic analysis of fluids and fluid-structure interactions. This module of COMET is used to analyze noise fields within enclosures such as automotive interiors and evaluate acoustic performance of products that radiate noise. BEAT consists of many advanced features that are useful in evaluating and improving the acoustic performance of products in many industries.
