This Phase I SBIR proposal seeks to develop a solution to integrate the high-fidelity, multi-physics ALE3D code into Endgame framework as a module that can be used with MEVA (a vulnerability/lethality assessment software) and other applications based on the Endgame framework software architecture.Currently, MEVA employs various fast-running engineering level models (FRMs) to assess the effects of munitions on structures and to perform lethality and vulnerability studies. Integrating the ALE3D code as an Endgame framework module could provide MEVA and other applications more accurate estimates of weapon survivability, weapons effects, and vulnerability or lethality assessments; and would be especially useful for the challenging cases where the synergistic effects of multiple weapon strikes are important. The software solution to be developed for the proposed effort consists of a simple, lightweight, and extensible software architecture that is capable of harnessing the capabilities in both codes and offering them for use to the end-user.The key deliverables for this project include a roadmap for fully implementing ALE3D into EF for use with MEVA as well as an EF plugin and demonstration of a fully coupled ALE3D-EF code for a multiple weapon strike scenario.software development,high-performance computing,weapons effects,penetration,lethality,vulnerability,Hydrocode,finite-elements
