Abstract
The Towed Acoustic Array Simulation (TAAS) computer program provides a fully dynamic simulation of the three dimensional geometric behavior of cable-towed flexible acoustic array systems, as well as other series-connected marine structures. Input consists of the system structural definition (component parts) and a scenario (deployment method and environmental forces). Output includes integration statistics and plots/tables/files of state variable data, tensions, and element angles. Features include modular part definitions, unrestricted generalized constrained motions, cable winching, non-linear tensions, torque-balanced elments, parallel stress elements (VIMs), non-uniform drag, and general fluid-velocity and external force fields. The method of lines is used to generate the coupled differential equations that model the system (a lumped-element formulation). Numerical integration of the equations is performed by standardized, error-controlled software for stiff systems.
