摘要: Wave propagation can be modeled by second-order hyperbolic partial differential equations. Efficient and reliable simulation of wave propagation requires stable and high-order accurate numerical methods. In the finite difference framework, it is challenging to derive a method that is both stable and high-order accurate for problems with physical boundaries, material interfaces and complex geometry. In this seminar, I will discuss the summation-by-parts concept that serves as a recipe for deriving provably stable and high-order spatial discretization for wave propagation problems.
