Computation of the Diffraction Transfer Matrix and the Radiation Characteristics in the open source zero-order BEM code NEMOH

International audienceThis paper presents a comparison of the hydrodynamic operators DTM and RC of a cylinder computed with the BEM solver NEMOH, in which the methodology of [2] has been implemented, and the ones obtained with the alternative approach developed and validated by [7]. In addition, a comparison of the wavefield of a small array of 4 freely floating cylinders computed using both the interaction theory and with a direct NEMOH calculation is shown
