Public Types

using Dof = std::array< double, 3 >
 Three generalized loads or coordinates: (heave, roll, pitch) or (surge, sway, yaw).
 
using Loads = std::array< double, 6 >
 Generalized loads on the six modes, ordered surge, sway, heave, roll, pitch, yaw [N, N m].

Member Function Documentation

◆ ExtraLoads()

virtual Loads WaveHull::ExtraLoads ( double  ,
const double *  ,
const Dof &   
) const
inlineprotectedvirtual

Loads a derived model adds, at time T, for the model-global state X and the hull velocity velocity (u, v, r). The base adds none.

Reimplemented in WavePropulsionHull.

◆ ExtraLoadsVelocityJacobian()

virtual std::array< Dof, 6 > WaveHull::ExtraLoadsVelocityJacobian ( const Dof &  ) const
inlineprotectedvirtual

d(ExtraLoads)/d(u, v, r), one row per load, with the derived model's inputs held fixed. Called from OdeJacobian, which has no model-global state; the base adds none.

Reimplemented in WavePropulsionHull.
