Simulating HEL Lethality with Complex Cad Geometries

Abstract

The US Navy has initialized research and development of shipborne high energy lasers (HEL) to counter anti-ship cruise missiles (ASCM) at terminal ranges. The previous modeling method for HEL lethality in COMSOL could not model complex geometry, preventing proper planning against such threats. Evolving from a two-dimensional to a three-dimensional environment required additional studies in error tolerances, accurate melt velocities, and meshing methods - ultimately enabling the use of computer-aided design (CAD) models. Using such models will allow accurate analysis of HEL lethality against specific threats, resulting in proper tactics and firing doctrine to ensure the ships defense.
