Scientific paper

Adaptive mesh refinement (AMR) has been used for improving computational resolution on hyperbolic problems when resources are limited. For a mature Eulerian multi-material shock-physics code like CTH, adaptivity is considered a natural next step in code development. Recent work has demonstrated the utility of AMR for studying shock processes in 2-D heterogeneous targets for planetary impact applications. In this study, even more complex targets such as a pre-fractured 433 Eros are being simulated with 3-D AMR.
