title = "A large scale analysis for ultrasonic wave propagation using parallelized FDTD method",
abstract = "A finite difference time domain method (FDTD) is based on a grid-based time domain differential technique, in which wave equations are solved in a leapfrog manner. It is required to discretize a whole target domain into computational grids with an adequate size. Therefore computational burden increases if the computational domain is much larger than the wave length. To solve such a large-scale problem in high speed, we apply a parallel computing technique to the FDTD. OpenMP is an interface to execute program codes in parallel using a shared memory system of computers. As an example of large-scale analysis, SH wave propagations in concrete material are demonstrated in this study.",
