Hydrodynamic Body Block
• Include blocks for calculating all the different forcing terms
Body Block
Non-Hydro Block
• Everything is zero except for weight and buoyancy
Note: Connection forces between multiple bodies from the joint/PTO are handled by Simscape Multibody

Hydrodynamic Body Block:Wave Diffraction and Excitation Force Calculation Block
• Pre-calculated waves.waveAmpTime is not used for wave diffraction and excitation force calculation, except when user-defined time-series option is used.

Hydrodynamic Body Block:Wave Radiation Force Calculation Block
• Added-mass term is a function of acceleration. Therefore, a Transport Delay block is used to break the algebraic loop• Variable Time-Step (ode45) option is available in WEC-Sim. However, the Convolution Integral block is always
calculated using a fixed-time step.
