ALE-AMR
An Open-science Three-dimensional Multiphysics Code for Collaboration on Science Applications
Developed by LBNL, LLNL, UCSD and UCLA
ALE-AMR is both an open science NERSC code and a methodology for modeling a variety of regimes ranging from hot radiating plasmas and warm dense matter to cold fragmenting solids. Applications of the ALE-AMR code include laser/target effects on the NIF laser at LLNL, ion beam target performance on the NDCX-I/NDCX-II experiment at LBNL, and plasma/solid interactions. The code combines Arbitrary Lagrangian Eulerian (ALE) hydrodynamics with Adaptive Mesh Refinement (AMR). Also included is a flexible strength/failure framework that can store persistent data required for accurate material failure models. Radiation diffusion in included via an operator spliting technique. Various surface tension models are also being developed for the code.
