✦ Synopsis

Time domain simulations of nonlinear motions of two-dimensional floating bodies in waves are presented. The so called 'body exact' approach is adopted in a numerical wave tank. A new scheme for pressure evaluation on the wetted hull is developed and systematically used with good results in terms of accuracy and stability. Strongly flared geometries are successfully handled even at very large amplitude motions. The validation of the code is carried out according to the 20th ITTC Seakeeping Committee recommendations through internal checks of consistency and through comparisons with available experimental data.
