excite_at_position()

void MayaFlux::Nodes::Network::ModalNetwork::excite_at_position	(	double	position,
		double	strength = 1.0
	)

Excite modes based on normalized strike position.

Parameters

position	Normalized position (0.0 = node, 1.0 = antinode)
strength	Overall excitation strength

Amplitude distribution follows spatial mode shapes:

• Position 0.5 excites all modes equally (center strike)
• Position 0.0 or 1.0 excites odd modes only (edge strike)
• Intermediate positions create physical strike distributions
