Time-Dilation Methods for Extreme Multiscale Timestepping Problems
Many astrophysical simulations involve extreme dynamic range of timescales around 'special points' in the domain (e.g. black holes, stars, planets, disks, galaxies, shocks, mixing interfaces), where processes on small scales couple strongly to those on large scales. Adaptive resolution, multi-physics, and hybrid numerical methods have enabled tremendous progress on the spatial, physics, and numerical challenges involved. But often the limiter for following the long timescales of global evolutio…

50 years ago tonight, the jerry garcia band returns home to keystone #berkeley following their east coast tour. a nice audience tape by castelli & menke. https://archive.org/details/jg75-11-0…
