A Finite Element Model for Acoustic Radiation

Numerical treatment of acoustic problems with the smoothed finite element method

“…There is extensive interest in the search for simple, efficient, and accurate numerical methods that are applicable to acoustic problems. Many researchers have studied many different numerical methods in order to improve the solution of acoustic problems, such as the finite element method (FEM) [1][2][3][4][5] and the boundary element method (BEM) [6]. There are also several other numerical methods that have been used to solve acoustic problems.…”

A method for multi-frequency calculation of boundary integral equation in acoustics based on series expansion

“…The finite element method (FEM) [1,2] and boundary element method (BEM) are used very often to solve acoustical problems. By virtue of semi-analytics, reducing dimension and high accuracy, the BEM is more effective than the FEM in calculation of sound radiations.…”
