Simulating HEL Lethality with Complex CAD Geometries is a Naval Postgraduate School thesis by Alex J. Shelander.
The US Navy has initiated research and development into shipborne high-energy lasers (HEL) for countering anti-ship cruise missiles (ASCM) in the terminal phase. The existing modeling technique for assessing HEL lethality in COMSOL could not accommodate intricate geometries, limiting the ability to strategize against these threats effectively. The transition from a two-dimensional to a three-dimensional framework necessitated further exploration into error tolerances, precise melt velocities, and meshing methods. This progression ultimately paved the way for integrating computer-aided design (CAD) models.
Utilizing these models will facilitate accurate evaluations of HEL lethality against specific threats. This, in turn, will enable the development of suitable tactics and firing protocols to ensure the ship’s defense. The shift to a three-dimensional environment significantly enhances the Navy’s capacity to counteract terminal-range anti-ship cruise missiles by deploying high-energy lasers.
