Time-Domain Simulations of Problems in Ocean Acoustics

Abstract

We have focused our attention on the development and use of finite-difference time-domain (FDTD) methods. Various forms of these time-domain techniques, which are flexible, robust, and generally simple to implement, have been used in a variety of disciplines to solve a wide range of problems. We have worked, and continue to work, to establish the accuracy of our proposed acoustic FDTD techniques by comparing numeric results to exact solutions for canonical problems or to results obtained using other numerical methods.
