Synthetik Presenting 'Coupled FSI Computations for Close-In UNDEX' at USNCCM 16

Accurate prediction of underwater explosion (UNDEX) damage against surface and subsurface vessels and structures is an important aspect of naval weapon system engineering, maritime lethality assessment, and protective design. The physical properties of water make this a challenging problem, as deformation of the target modifies the pressure in the surrounding fluid, changing the explosive loading. Consequently, it is necessary to couple the fluid/explosive modeling with the structure simulation. Thus, the underwater damage prediction problem is complex, extremely non-linear and target deformation can alter the effective load imposed by a weapon.

Our briefing at USNCCM16 describes such a coupled analysis leveraging the opensource blastFoam and solids4foam solvers, and compares with simulation outputs and experimental data generated by the U.S. Navy.
