Ely is on a distinguished road

Does anyone know how to perform a decay test with Ansys AQWA? I have just read on the AQWA theory manual (Chapter 14: Extended functionalities) that:

"The damping property for a specified degree of freedom of a floating structure can be estimated using a numerical twang test record. The structure center of gravity is shifted by a distance along the specified degree of freedom from its equilibrium position in still water at time. A time history of its freely-decaying response can then be calculated by an Aqwa time domain analysis."

but I am afraid that aqwa-librium is needed, which is not available with my license (I only have access to Hydrodynamic Diffraction and Hydrodynamic Time Response)
