Member Function Documentation

◆ Clone()

WsfAtmosphericDragTerm * WsfAtmosphericDragTerm::Clone ( ) const

inlineoverridevirtual

Return a copy of this object. Must be implemented by all derived types. If cloning is impossible, a WsfUncloneableException should be thrown.

Implements WsfOrbitalDynamicsTerm.

References WsfAtmosphericDragTerm().

◆ ComputeAcceleration()

UtVec3d WsfAtmosphericDragTerm::ComputeAcceleration	(	double	aMass,
		const UtCalendar &	aTime,
		const UtVec3d &	aPosition,
		const UtVec3d &	aVelocity ) const

overridevirtual

Return the acceleration in the ECI frame.

This routine computes the acceleration represented by this term that would be experienced by a body of the given aMass at the given aTime, aPosition and aVelocity. The given aPosition and aVelocity are in the ECI frame, and the returned acceleration is also in the ECI frame.

Parameters

aMass	- The mass of the object that would experience this dynamical term.
aTime	- The time at which the acceleration is being computed.
aPosition	- The position of the body that would experience this acceleration.
aVelocity	- The velocity of the body that would experience this acceleration.

Returns: - The acceleration corresponding to this dynamical term.

Implements WsfOrbitalDynamicsTerm.

References WsfOrbitalDynamicsTerm::GetDynamics().

◆ GetAtmosphereModelName()

const std::string & WsfAtmosphericDragTerm::GetAtmosphereModelName ( ) const

inline

Get the name of the atmosphere model used by this term to compute the density.

◆ GetCrossSectionalArea()

double WsfAtmosphericDragTerm::GetCrossSectionalArea ( ) const

inline

Return the cross sectional area in m^2 used by this term.

◆ GetDragCoefficient()

double WsfAtmosphericDragTerm::GetDragCoefficient ( ) const

inline

Return the drag coefficient used by this term.

◆ GetScriptClassName()

const char * WsfAtmosphericDragTerm::GetScriptClassName ( ) const

inlineoverride

◆ GetTermType()

std::string WsfAtmosphericDragTerm::GetTermType ( ) const

inlineoverridevirtual

Return a string indicating the type of term.

Implements WsfOrbitalDynamicsTerm.

References cTYPE.

◆ Initialize()

bool WsfAtmosphericDragTerm::Initialize ( const WsfOrbitalDynamics & aDynamics )

overridevirtual

Initialize the term.

This is called when the owning WsfOrbitalDynamics is initialized. This enables terms that might need to inspect their owning dynamics.

Parameters

aDynamics - the dynamics to which this term belongs.

Reimplemented from WsfOrbitalDynamicsTerm.

References wsf::space::AtmosphereSimulationExtension::Get(), wsf::space::AtmosphereSimulationExtension::GetAtmosphere(), WsfOrbitalDynamics::GetSimulation(), and WsfOrbitalDynamicsTerm::Initialize().

◆ ProcessInput()

bool WsfAtmosphericDragTerm::ProcessInput ( UtInput & aInput )

overridevirtual

Process input from a generic source.

Examine the current input command. If it is NOT one of the commands recognized by this class then it simply returns 'false'. If it is one of the commands recognized by this class then it processes the command and returns 'true'.

Parameters

aInput a reference to a UtInput object.

Returns: 'true' if the command was one recognized by the class or 'false' if not.

Exceptions

UtInput::ExceptionBase (or an object derived from it) if the command was recognized but contains some sort of error.

Note: If a derived class does not recognize the command (i.e.: the return value is false) then it should call the base class ProcessInput method. This chain should continue until either the command is recognized or the top-level base class is encountered.

Reimplemented from WsfObject.

◆ SetAtmosphereModelName()

void WsfAtmosphericDragTerm::SetAtmosphereModelName ( const std::string & aModelName )

inline

Set the name of the atmosphere model used by this term to compute the density.

◆ SetCrossSectionalArea()

void WsfAtmosphericDragTerm::SetCrossSectionalArea ( double aCrossSectionalArea )

inline

◆ SetDragCoefficient()

void WsfAtmosphericDragTerm::SetDragCoefficient ( double aDragCoefficient )

inline

Set the drag coefficient used by this term.
