Data for: Numerically fitted polynomial expressions for added mass, radiation damping and wave excitation of 2D rectangular floating bodies in finite depth waters

This dataset accompanies the paper "Numerically fitted polynomial expressions for added mass, radiation damping and wave excitation of 2D rectangular floating bodies in finite depth waters" by Omar Mohamad and Luca Martinelli. The dataset contains figures comparing the fitted expressions with the finite-element (FEM) results for the investigated rectangular floating-body geometries, including added-mass and radiation-damping coefficients and complex wave-excitation loads in surge, heave and pitch. These cover 37 geometries used to fit 14 multivariate Chebyshev polynomial expressions and 24 additional geometries used for independent verification. The repository also includes: An Excel workbook containing the fitted polynomial coefficients and a calculator for evaluating the hydrodynamic quantities for user-defined geometries and wave periods. Comparison figures supporting the validation and verification of the proposed formulations. The comparisons with the small-clearance solution of Drobyshevski (2004) for the 15 geometries with d/h ≥ 0.6.
