Abstract

Results from Blind Test Series 1, part of the Collaborative Computational Project in Wave Structure Interaction (CCPWSI), are presented. Participants, with a range of numerical methods, simulate blindly the interaction between a fixed structure and focused waves ranging in steepness and direction. Numerical results are compared against corresponding physical data. The predictive capability of each method is assessed based on pressure and runup measurements. In general, all methods perform well in the cases considered; however, there is notable variation in the results (even between similar methods). Recommendations are made for appropriate considerations and analysis in future comparative studies.
