The project is directed towards the development and validation of a numerical technique based on Energy Flow Analysis (EFA) for the analysis of high frequency vibroacoustic problems. The energy flow equations are solved using fintie element methods for structural and acoustic domains. Additionally, boundary element method is also used to model acoustic domains.

Major accomplishments of the project include the development of a new method for interior noise prediction, development of an extensive library of structural and noise control elements, development of the joint element, development and incorporation of the energy boundary element method for the modeling of acoustic domain, development of a hybrid method for the accurate modeling of local excitation, efficient solution methods, and development of method for the automatic identification of point, line and area junctions at geometric and material discontinuities.
