Wind¶

struct nmeasim::core::model::Wind · Library API

True and apparent wind measured on board.

#include <nmeasim/core/model/vessel_state.hpp>

Declared in src/core/include/nmeasim/core/model/vessel_state.hpp (line 140)

The apparent values are derived from the true wind and the vessel's motion by physics::apparent_wind on every tick.

Summary¶

Public member functions

Name	Description
`true_angle_relative_deg()`	Returns the angle the true wind comes from relative to the bow.

Public data members

Name	Description
`true_direction_deg`	Direction the true wind blows from, in degrees true, in [0, 360).
`true_speed_kn`	True wind speed, not negative; sent in MWD and the true MWV.
`apparent_angle_deg`	Angle the apparent wind comes from relative to the bow, clockwise, in [0, 360).
`apparent_speed_kn`	Apparent wind speed, sent in the relative MWV.

double true_angle_relative_deg(double heading_true_deg) const noexcept

Returns the angle the true wind comes from relative to the bow.

Parameters

Name	Type	Description
`heading_true_deg`	`double`	Heading of the bow in degrees true.

Returns double: The angle clockwise from the bow, in [0, 360).

double true_direction_deg{0.0}

Direction the true wind blows from, in degrees true, in [0, 360).

double true_speed_kn{0.0}

True wind speed, not negative; sent in MWD and the true MWV.

double apparent_angle_deg{0.0}

Angle the apparent wind comes from relative to the bow, clockwise, in [0, 360).

double apparent_speed_kn{0.0}

Apparent wind speed, sent in the relative MWV.
