Detailed Description

The casting structure as its wake caster sees it.

Nodes and panels are numbered from zero; a panel is a triangle of three nodes. State vectors are the global FhSim state vectors handed to PreOdeFcn.

Member Function Documentation

CableHydrodynamicForce()

virtual void net_wake::WakePanelSource::CableHydrodynamicForce ( double  T, const double *  X, double  force[3]  ) const

inlinevirtual

The hydrodynamic force on the structure's cable elements (and the floats and sinkers on them) in the current flow, which the lumped source leaves out (QF9, MARE-0141). It is the cable force at the flow the cables see minus the cable force when the water follows each element, so the tension, the weight and the wave excitation drop out. A structure without cables keeps the default, zero.

Parameters

[in]	T	Simulation time, s.
[in]	X	The state vector.
[out]	force	Sum over the cable elements, N, NED.

EvaluatePanel()

virtual PanelEvaluation net_wake::WakePanelSource::EvaluatePanel ( const double *  X, int  panel, const double  elementVel[3], const double  waterVel[3]  ) const

pure virtual

Evaluates a panel's load law at a given panel velocity and free-stream water velocity.

Parameters

[in]	X	The state vector; the panel geometry and solidity come from it.
[in]	panel	The panel.
[in]	elementVel	Velocity of the panel, m/s, NED.
[in]	waterVel	Free-stream water velocity at the centroid, m/s, NED.

Returns

The panel load, the panel's area and the wake solidity (PanelEvaluation::solidity).
