Our goal is to construct a nonstandard finite difference (NSFD) scheme for the linearized Euler partial differential equations (PDE’s) modeling acoustic propagation in one space dimension. Unlike other works on this discretization problem, we formulate it in terms of a single, second-order PDE rather than as two separate first-order equations. The important mathematical features of this scheme are discussed. c ⃝ 2014 International Association for Mathematics and Computers in Simulation (IMACS… CONTINUE READING
