Parameterisation

Here you can see and edit the parameters of the selected device. Confirm changes with "Apply" and the parameter will change immediately.

Basic parameters:

Volume, cross-sectional waterplane area and buoyancy stiffness

The graph on the left displays the volume and the cross-sectional area of the floater in dependence of the subermergence level. The graph on the right plotes the buoyancy stiffness, the negative spring stifness and the resulting stiffness curve assuming a fixed slider.

Excitation force

Excitation force coefficients with real (left) and imaginary part (right).

Hydrodynamic radiation impedance

Radiation resistance (left) and added mass (right).)

Generator efficency

Generator efficiency over (total) applied power.
