Second Order Difference- and Sum-Frequency Wave Loads in the Open-Source Potential Flow Solver NEMOH
Theoretical and numerical aspects of the open-source potential flow boundary element solver, NEMOH, for the first order hydrodynamic coefficients computations in the frequency domain are described in [Babarit, A. and Delhommeau, G., 2015]. [Philippe, M. et al., 2015] described the implementation and...
