Numerical Simulation of Elastic Waves

The PML boundary implementation discussed in this article for elastic wave numerical simulation offers valuable guidance for those beginning their study of seismic wave propagation theory. In this field, researchers can utilize numerical methods to model elastic wave propagation patterns, helping to better understand the transmission mechanisms of seismic waves within the Earth's interior. Such simulations typically involve solving wave equations using finite-difference or finite-element methods, often implemented through matrix operations and time-stepping algorithms in programming environments like MATLAB or Python. This research provides more accurate data and methods for earthquake prediction and disaster prevention, contributing to the development of robust computational models that can handle complex geological structures. Furthermore, the study opens new research directions for experts in related fields, enabling deeper investigation into elastic wave numerical simulation applications. The implementation often includes features like stability analysis, dispersion correction, and parallel computing optimization to enhance simulation accuracy and efficiency, thereby providing strong support and guidance for advancing technologies and methodologies in relevant domains.
