Abbasnia, A. and Guedes Soares, C. (2024), On the computational costs of potential models for floating bodies in waves, Advances in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor and Francis Group, London, UK¸ pp. 79-87.
The potential flow theory has been used to determine the response of floating bodies in waves and the boundary integral equation was implemented to solve the Laplace equation. In the linear potential models, the complexity of the free surface boundary conditions leads to the boundary conditions linearized and it makes the validity range of the solution shortened for large amplitude response for non-wall sided bodies. To treat the exact free surface boundary conditions, fully nonlinear potential models have been developed based on the mixed Eulerian-Lagrangian methods. The burden of computation of the fully nonlinear model is extremely larger than linear models which draws a rationale of this paper for delving into the results of linear and fully nonlinear models to measure the cost of computation. Hence non-wall-sided bodies are taken into comparison of the responses obtained from the in-house linear and fully nonlinear models which were developed previously.
