◆ AddNodeForces()

void NetElement3NWithConstraints::AddNodeForces	(	const hydrodynamics::PanelLoadLaw &	law,
		const hydrodynamics::Fluid &	fluid,
		const double *const	posA_ned,
		const double *const	posB_ned,

	)		const

Adds this element's hydrodynamic load and weight in water to the forces on its nodes.

The load is one evaluation of law by the shared panel core (NetElement3NForces.h), at the solidity of the element's rule (NetSolidity.h) and the mesh opening angle of the given positions, shared equally between the three nodes. The element adds no twine tension and no damping, as before MARE-0095.

Parameters

[in]	law	The panel load law.
[in]	fluid	Density and kinematic viscosity.
[in]	posA_ned	Position of node A, global frame.
[in]	posB_ned	Position of node B, global frame.
[in]	posC_ned	Position of node C, global frame.
[in]	velA_ned	Velocity of node A, global frame.
[in]	velB_ned	Velocity of node B, global frame.
[in]	velC_ned	Velocity of node C, global frame.
[in]	waterVel_ned	Free-stream water velocity at the element, global frame.
[in,out]	nodeAforce_ned	Accumulator for the force on node A.
[in,out]	nodeBforce_ned	Accumulator for the force on node B.
[in,out]	nodeCforce_ned	Accumulator for the force on node C.
[in]	clampLog	Receives the load law's clamp flags (MARE-0140); none when null.

◆ EvaluatePanelLoad()

hydrodynamics::PanelLoad< double > NetElement3NWithConstraints::EvaluatePanelLoad	(	const hydrodynamics::PanelLoadLaw &	law,
		const hydrodynamics::Fluid &	fluid,
		const double *const	posA_ned,
		const double *const	posB_ned,
		const double *const	posC_ned,
		const double	elementVel[3],
		const double	waterVel_ned[3],
		double &	area
	)		const

Evaluates the panel load law on the element without adding any node force.

The same evaluation as AddNodeForces makes, at a given element velocity instead of the mean of the node velocities; a wake caster uses it for the source strength (fhsim_environment/PanelSourceSet.h). As NetElement3N::EvaluatePanelLoad.

Parameters

[in]	law	The panel load law.
[in]	fluid	Density and kinematic viscosity.
[in]	posA_ned	Position of node A, global frame.
[in]	posB_ned	Position of node B, global frame.
[in]	posC_ned	Position of node C, global frame.
[in]	elementVel	Velocity of the element, global frame.
[in]	waterVel_ned	Free-stream water velocity at the element, global frame.
[out]	area	The element's area at the given positions, m^2.

Returns: The panel load.
