Struct to hold and manage turbine-specific data.

This struct contains data for a single turbine, including the number of blades, mesh data for various components (hub, nacelle, blade roots, blade nodes), and blade node mappings.

Constructor & Destructor Documentation

◆ TurbineData()

kynema::util::TurbineData::TurbineData ( const TurbineConfig & tc )

inline

Constructor for TurbineData based on a TurbineConfig object.

This constructor initializes the turbine data in AeroDyn/InflowWind compatible format based on the provided TurbineConfig object in 7x1 arrays i.e. Kynema format.

Parameters

tc	The TurbineConfig object containing the initial state of the turbine

Member Function Documentation

◆ GetBladeNodeLoad()

std::array< double, 6 > kynema::util::TurbineData::GetBladeNodeLoad	(	size_t	blade_number,
		size_t	node_number
	)		const

inline

Gets the blade node loads based on blade number and node number.

This method returns the blade node loads based on the provided blade number and node number. It simplifies the process by abstracting away the indexing logic.

Parameters

blade_number	The number of the blade to update.
node_number	The number of the node to update within the specified blade.

◆ NumberOfBlades()

size_t kynema::util::TurbineData::NumberOfBlades ( ) const

inline

Returns the number of blades as size_t.

◆ SetBladeNodeMotion()

void kynema::util::TurbineData::SetBladeNodeMotion	(	size_t	blade_number,
		size_t	node_number,
		const std::array< double, 7 > &	position,
		const std::array< double, 6 > &	velocity,
		const std::array< double, 6 > &	acceleration
	)

inline

Sets the blade node values based on blade number and node number.

This method updates the blade node values in the mesh based on the provided blade number and node number. It simplifies the process of updating blade node values by abstracting away the indexing logic.

Parameters

blade_number	The number of the blade to update.
node_number	The number of the node to update within the specified blade.
position	The new position of the node [x, y, z, qw, qx, qy, qz]
velocity	The new velocity of the node [u, v, w, p, q, r]
acceleration	The new acceleration of the node [u_dot, v_dot, w_dot, p_dot, q_dot, r_dot]

◆ SetBladeRootMotion()

void kynema::util::TurbineData::SetBladeRootMotion	(	size_t	blade_number,
		const std::array< double, 7 > &	position,
		const std::array< double, 6 > &	velocity,
		const std::array< double, 6 > &	acceleration
	)

inline

Sets the blade root values based on blade number.

This method updates the blade root values in the mesh based on the provided blade number and node number. It handles orientation conversion so Z is along blade axis.

Parameters

blade_number	The number of the blade to update.
position	The new position of the node [x, y, z, qw, qx, qy, qz]
velocity	The new velocity of the node [u, v, w, p, q, r]
acceleration	The new acceleration of the node [u_dot, v_dot, w_dot, p_dot, q_dot, r_dot]

◆ SetHubMotion()

void kynema::util::TurbineData::SetHubMotion	(	const std::array< double, 7 > &	position,
		const std::array< double, 6 > &	velocity,
		const std::array< double, 6 > &	acceleration
	)

inline

Sets the hub motion values.

This method updates the hub motion values.

Parameters

position	The new position of the node [x, y, z, qw, qx, qy, qz]
velocity	The new velocity of the node [u, v, w, p, q, r]
acceleration	The new acceleration of the node [u_dot, v_dot, w_dot, p_dot, q_dot, r_dot]

◆ SetNacelleMotion()

void kynema::util::TurbineData::SetNacelleMotion	(	const std::array< double, 7 > &	position,
		const std::array< double, 6 > &	velocity,
		const std::array< double, 6 > &	acceleration
	)

inline

Sets the nacelle motion values.

This method sets the nacelle motion values.

Parameters

position	The new position of the node [x, y, z, qw, qx, qy, qz]
velocity	The new velocity of the node [u, v, w, p, q, r]
acceleration	The new acceleration of the node [u_dot, v_dot, w_dot, p_dot, q_dot, r_dot]

◆ Validate()

void kynema::util::TurbineData::Validate ( ) const

inline

Member Data Documentation

◆ blade_nodes

MeshData kynema::util::TurbineData::blade_nodes

◆ blade_nodes_to_blade_num_mapping

std::vector<int32_t> kynema::util::TurbineData::blade_nodes_to_blade_num_mapping

Mapping of blade nodes to blade numbers (1D array)

This vector stores the blade number (1-based index) for each blade node. It allows quick lookup of which blade a particular node belongs to. The size of this vector is equal to the total number of blade nodes across all blades.

◆ blade_roots

MeshData kynema::util::TurbineData::blade_roots

◆ hh_vel

std::array<float, 3> kynema::util::TurbineData::hh_vel

◆ hub

MeshData kynema::util::TurbineData::hub

◆ n_blades

int32_t kynema::util::TurbineData::n_blades

◆ nacelle

MeshData kynema::util::TurbineData::nacelle

◆ node_indices_by_blade

std::vector<std::vector<size_t> > kynema::util::TurbineData::node_indices_by_blade

Unique indices of nodes for each blade (2D array)

This is a vector of vectors where each inner vector contains the unique indices of nodes belonging to a specific blade. The outer vector's size is equal to the number of blades, and each inner vector's size is equal to the number of nodes on that blade. This structure allows quick access to all nodes of a particular blade.
