Abstract
SBD for ship hydrodynamics merges traditional fields of resistance and propulsion, seakeeping, and maneuvering, which with inclusion of environmental effects will revolutionize the design process and offers possibility for innovative out-of-the box concepts for future ships to meet the challenges of the 21st century. Development of SBD involves a new paradigm for hydrodynamics research in which CFD, EFD, UA are conducted simultaneously for benchmark geometries and conditions using an integrated approach along with optimization methods, all of which serve as internal engine guaranteeing simulation fidelity. Present paper describes research at IIHR in major components of SBD for ship hydrodynamics through overview the status of their application to traditional fields and future directions. Prognosis for realization practical applications is also discussed. 1. INTRODUCTION Rapid advancements in simulation technology are revolutionizing engineering practice, including ship design, as simulation-based design (SBD) and ultimately virtual reality are replacing current reliance on experimental observations and analytical methods. It is not unreasonable to expect a major shift in how scientific method forms its basis of conceptual truth, a shift from reliance on observations, based on experiments, to reliance on logic, based on simulation with profound similarities and differences to transition from Aristotelian to Galilean scientific methods, as occurred in 16th-18th centuries. SBD covers a broad range from computerized systems to solutions of physics based.
