Time-domain Numerical Solution of the Wave Equation
نویسنده
چکیده
This paper presents an overview of the acoustic wave equation and the common time-domain numerical solution strategies in closed environments. First, the wave equation is presented and its qualities analyzed. Common principles of numerical approximation of derivatives are then reviewed. Based on them, the finite difference (FD) and the finite element methods (FEM) for the solution of the wave equation are presented along with algorithmic and practical considerations.
