Efficient Approaches for Ship Response Statistics using RANS

摘要

We present case studies of two approaches to efficiently obtain shipresponse extremes from time domain simulations. These approaches,namely, the so-called coefficient of contribution method and responseconditionedwave episodes, allow long-term statistical predictions basedon a combination of frequency domain analyses with a limited numberof time-domain simulations with computationally expensive methods. Inthe present case, the time domain code is a RANS solver coupled to afinite element structure solver.
