Event Details & Abstract: 

In integrating the equations of hydrodynamics, standard numerical techniques are very powerful at shock-capturing, but use a fixed grid, allowing fluid to be passed from grid cell to grid cell. New numerical methods have emerged over the past few years which perform calculations on a more generalized mesh, allowing the grid to move with the flow, but while still preserving the desired shock-capturing properties of fixed-grid methods. The most well-known of these methods uses a Voronoi Tessellation to dynamically re-calculate the shape and size of computational zones as the move through the domain. I will discuss several implementations of such grids, with applications to protoplanetary disks, black hole binary systems, tidal disruption events, binary mergers, and relativistic jets.
