TY - CONF TI - On Implementing Cummins Equation to Represent Accurate Wave Radiation Forces in Modelica AU - Menon, A AU - Haider, A AU - Bubbar, K T2 - 42nd International Conference on Ocean, Offshore & Arctic Engineering (OMAE 2023) C1 - Melbourne, Australia AB - This work explores the development of a Modelicaâ„¢ compliant Ocean Engineering Toolbox (OET). Focusing on a symbolic solution to the Cummins equation for a floating, heaving body subject to polychromatic wave excitation forces, three formulations of the radiation convolution (symbolic, numerical, and state-space) are investigated and validated using the benchmark WEC-Sim. The presented formulation is tested using the model parameters of the Reference Model-3 (RM3) heaving point absorber Wave Energy Converter (WEC). For a preset excitation force, a 300-second simulation of the OET yields accurate results when compared to WEC-Sim. Computational speed measurements also indicate significant improvements in simulation efficiency compared to solving the radiation convolution integral numerically.
