Acoustic Wave Equation Wavefield Simulation

This is a MATLAB-based program designed for simulating wavefields governed by the acoustic wave equation. The implementation utilizes both Finite Difference Method (FDM) and Finite Element Method (FEM) to solve the wave equation numerically. Key algorithmic features include adjustable grid resolutions and time steps for performance optimization, where the grid spacing controls spatial accuracy and the time step size ensures numerical stability through the Courant-Friedrichs-Lewy (CFL) condition. The program incorporates customizable source and receiver configurations, allowing users to define source signals (e.g., Ricker wavelets) and receiver positions programmatically for precise control and observation of wavefield characteristics such as reflection patterns and propagation paths. This simulation tool aids in understanding wave propagation and reflection phenomena, providing valuable insights for acoustic research and applications in fields like seismology and non-destructive testing.
