Lethality Impact Maritime Analysis (LIMA) Toolset

The objective of the proposed project is to formulate, design and implement the Lethal Impact Maritime Analysis (LIMA) toolset. LIMA brings the latest modeling and simulation technology into vulnerability and lethality (V/L) assessment for maritime structures to serve US NAVY needs. LIMA comes with an intuitive graphical user interface enabled by fault-tree and stochastic analysis modules, a parametric geometric modeling engine featuring Illinois Rocstar's open-source CAD/meshing software (NemoSys), and a modular, extensible application coupling framework powered by Illinois Rocstar's open-source multiphysics application coupling toolkit (IMPACT). Leveraging existing DoD software, a set of fast running models (FRMs) will be offered for quick/efficient V/L assessment of user-developed targeting scenarios. A few open-source and government-owned high-performance physics solvers will also be provided to augment user's ability to carry out high-fidelity (HF) assessment with minimal additional effort. The Phase I effort features design of LIMA's core application module, identification and detailed investigation of its FRMs and HF tools, initial prototyping, and feasibility assessment. The subsequent phases will include full implementation, testing and performance tuning of LIMA along with its commercialization.
