Two-Dimensional Acoustic Wave Staggered Grid Tenth-Order Finite Difference

The two-dimensional acoustic wave staggered grid tenth-order finite difference program is a computational implementation designed to simulate acoustic wave propagation patterns and calculate wavefield amplitudes. This program employs a staggered grid configuration where velocity and stress components are defined at different grid points, coupled with tenth-order finite difference operators that provide superior numerical dispersion control compared to lower-order schemes. The algorithm typically implements perfectly matched layer (PML) boundary conditions to minimize artificial reflections and uses memory-optimized data structures for efficient wavefield storage. Key computational aspects include: the separation of wave equations into velocity-stress formulations, time-stepping using leapfrog or Runge-Kutta methods, and spatial derivatives calculated through tenth-order difference coefficients that enhance simulation accuracy while maintaining computational stability through appropriate Courant-Friedrichs-Lewy (CFL) conditions. This implementation enables researchers to better understand acoustic wave propagation characteristics across different media, facilitating predictive modeling and problem-solving capabilities. By utilizing this high-precision numerical scheme, users can perform more accurate and detailed analysis of wave transmission processes, thereby providing robust support for research in related fields. Furthermore, this methodology holds significant application value across multiple disciplines including acoustics, seismology for subsurface imaging, medical ultrasound imaging, and non-destructive testing applications.
