Comparison of fully non linear and weakly nonlinear potential flow solvers for the study of wave energy converters undergoing large amplitude of motions
International audience We present a comparison between two distinct numerical codes dedicated to the study of wave energy converters. Both are developed by the authors, using a boundary element method with linear triangular elements. One model applies fully nonlin-ear boundary conditions in a numeri...
