WHAT:
ShipTech 2010 Presentation: Efficiency Through Integrated Tools
Initial hull design requires that global loads and stresses be considered as one of the first steps in the design of a ship. The process usually starts with a naval architect creating a rough full ship model that is optimized for global stresses. Local stresses for items like structural details and equipment foundations are typically modeled and simulated much farther into the design cycle by structural engineers.
The problem is that local details can affect the initial global response so the global simulation must be repeated every time a local component is added to the ship. Using an integrated process incorporating MAESTRO (global hull analysis) and NEi Nastran (local hull analysis), local details can easily and continuously be incorporated into a global model, allowing the global/local modeling and simulation process to be conducted much earlier in the design process than is typically done.
