Masonry gravity structures forming buildings, bridges and other constructions have been built for many centuries, but continue to pose challenges for engineers. Specifically, there is a need to more reliably understand and assess the safety of existing masonry buildings and bridges, and also to conceive more elegant and resource efficient structural solutions for use in new construction, using traditional and emerging new masonry materials. In the case of masonry arch forms, though ubiquitous in buildings and bridges, their mode of interaction with surrounding elements remains poorly understood, and more realistic modelling tools are required to address this.

The paper presents results from the Collaborative Computational Project in Wave Structure Interaction (CCP-WSI) Blind Test Series 2. Without prior access to the physical data, participants, with numerical methods ranging from low-fidelity linear models to fully nonlinear Navier-Stokes (NS) solvers, simulate the interaction between focused wave events and two separate, taut-moored, floating structures: a hemispherical-bottomed cylinder and a cylinder with a moonpool. The ‘blind’ numerical predictions for heave, surge, pitch and mooring load, are compared against physical measurements. Dynamic time warping is used to quantify the predictive capability of participating methods. In general, NS solvers and hybrid methods give more accurate predictions; however, heave amplitude is predicted reasonably well by all methods; and a WEC-Sim implementation, with CFD-informed viscous terms, demonstrates comparable predictive capability to even the stronger NS solvers. Large variations in the solutions are observed (even among similar methods), highlighting a need for standardisation in the numerical modelling of WSI problems.
