AbstractThis SBIR Phase I project aims at enabling the transformation of the computational capability for implosion developed under the ONR MURI and FNC programs on implosion from a research code to a reliable, high-performance, and user-friendly software for the prediction of implosion and its effects on near-by systems. To this effect, it focuses on developing a compact modeling procedure for underwater implosion that captures the critical parameters of this problem, is amenable to manual, semi-automatic, and automatic one- and three-dimensional analyses as needed, and offers robust and computationally efficient hydrostatic initiation procedures. It also focuses on designing, implementing within the software AERO-I, and demonstrating for sample relevant problems a prototype GUI for the above modeling procedure that ensures both its user-friendliness and reliability. The project also analyzes the technical feasibility of implementing the Tillotson EOS for water in the computational algorithms of the flow solver AERO-F. It also develops a blueprint for upgrading this solver to enable its operation on hexahedral meshes, as these reduce the computational complexity of the implosion simulation of submerged cylindrical geometries. To achieve the stated objective, this SBIR Phase I project also focuses on optimizing the CPU performance of AERO-F's implosion capabilities.
