Abstract: In this talk, high-order summation-by-parts (SBP) finite difference methods for time-dependent wave propagation problems will be discussed. It is well known that high-order finite difference methods have good properties for solving wave propagation problems efficiently. However, real-world problems often include complicated features such as complex geometries, non-linearities, or non-smooth data that may ruin the accuracy of SBP finite difference methods. In this talk, I will present methods for constructing accurate high-order finite difference schemes for problems including two such features: moving boundaries and moving point sources.
