内容記述タイプ Abstract
内容記述 Finite-difference time-domain (FDTD) acoustic simulation technique in generalized curvilinear coordinates using contravariant velocity and pressure as variables for two-step leapfrog time marching scheme is presented. The technique excels the conventional generalized curvilinear technique using contravariant velocity, covariant velocity and pressure as variables for three-step time marching, especially in that normal acoustic impedance boundary conditions which are indispensable in practical application are also presented. Validation of the technique through comparison against orthogonal FDTD with staircasing applied in irregularly-shaped sound field shows suppressions of phase error in initial time marching stage and diffusion from staircased boundaries.
