Topics:

Some recent development in high order methods for conservation laws and related equations will be discussed, such as FCT and flux limiter, MUSCL and slope limiter, finite difference and finite volume ENO/WENO schemes on rectangular and unstructured meshes; central scheme, central scheme on overlapping cells; discontinuous Galerkin method (DG), LDG and central DG on overlapping cells; Hierarchical reconstruction methods (HR) for reducing numerical artifacts (due to non smoothness of the solution) on unstructured triangular meshes; finite volume methods with HR etc. Some classical methods for solving Navier-Stokes equation of incompressible fluids will be introduced, such as the Marker-and-Cell method, projection method, mixed finite element methods etc. Interface tracking and capturing methods will be covered, including front-tracking, volume of fluids and the level set methods. Recent development on BFECC method and its limiting for solving time dependent Hamilton-Jacobi equations on regular or irregular meshes, and BFECC for solving Maxwell's equations for electromagnetic waves and for perfectly matched layers (PML). Recent development on neural network methods for solving conservation laws.
