The marine environment is harsh and unforgiving, and ship structures must accommodate this environment in a way that balances safety and cost. Optimized ship structure design will therefore encompass many disciplines—for example, naval architecture, hydrodynamics, material science, and engineering—while strictly adhering to industry codes, such as the American Bureau of Shipping (ABS), and end-user specifications, such as the US Navy’s SUBSAFE program requirements. Additionally, ship structures tend to be quite large—providing numerous simulation challenges, including time and memory required for simulation in addition to the specialized nature of ship simulation and loads.
The Abaqus Unified FEA product suite and Multiphysics solutions from SIMULIA provide the Shipbuilding industry with the tools needed to accurately and easily simulate realistic behavior of ship structures and loading. SIMULIA's Simulation Lifecycle Management strategy makes it possible for a company to manage its simulation data processes and applications to significantly improve its development process.
