The simulation software HydRA has been validated against WAMIT. The following presentation shows the comparisons between HydRA and WAMIT for the following quantities in both single body and multi-body scenarios:
Added Mass
Radiation Damping
Diffraction Force (Froude-Krylov + Scattering)
Response Amplitude Operator (RAO)
The input files, output files and complete set of plots can be accessed from the google drive folder here.
