This project focuses on developing and validating a numerical technique using Energy Flow Analysis (EFA) for high-frequency vibroacoustic problems. The energy flow equations are solved with finite element methods for structural and acoustic domains, and boundary element methods for acoustic domains. Major accomplishments include: A new method for interior noise prediction, an extensive library of structural and noise control elements, development of joint elements, inclusion of the energy boundary element method for modeling acoustic domains, a hybrid method for accurate local excitation modeling, efficient solution methods, and automatic identification of point, line, and area junctions at geometric and material discontinuities.
