An Automated Reachback Capability for Non-Ideal Airblast Calculations

Paul Yarrington, Sandia National Laboratory

Abstract:
Calculational studies of airblast effects using the SHAMRC code on massively parallel computer platforms will be presented for low-yield fallout-free height of burst (FFHOB) scenarios, with attention to dominant effects for regional targets. Scalability of calculations and requirements for achieving converged calculational results will be discussed, along with implications for compute resource requirements to provide a rapid reachback capability to support targeting decisions. A software framework will be described that provides capability for rapid turnaround of highly-automated calculations that account for key problem uncertainties, e.g. weapon CEP, to predict realistic non-ideal airblast effects from a low-yield FFHOB attack on a designated target site.
