Abstract:
Many complex physical phenomena, such as seismic wave propagation in the Earth and water flows in rivers, can be mathematically modeled by partial differential equations (PDEs). In realistic applications, these equations have heterogeneous material parameters and are posed on large domains with complicated geometry. To this end, exact solutions to the governing equations are not available. Instead, numerical modeling and simulation is a powerful tool to understand the underlying physical phenomena.
In this talk, I will introduce fundamental numerical techniques, including finite difference and finite element methods, for solving PDEs. I will then provide an overview of our work on computational methods for wave propagation and discuss their advantages and challenges in seismic applications. Special attention will be given to properties such as stability, accuracy and computational efficiency. While I will highlight their role in understanding seismic wave propagation, the methods presented are broadly applicable across various fields.
