Detailed Description

Force model for the first order approximation for a non-spherical gravitational source.

The model requires the value of the radius of the planet. The default units are for the Earth in orbital units.

Member Function Documentation

CalcAccelerationIJPerM()

double[] J2Gravity.CalcAccelerationIJPerM	(	double[]	rji,
		int	i,
		int	j,
		GravityState.NbodyState[]	nbodyStates
	)

Calculate the acceleration between bodies i and j.

Return the aij and aji accelerations because in some case (e.g one is oblate) they will not be equal and opposite!

Parameters

rji
i
j
nbodyStates

Returns

Implements IForceDelegate.

CalcAccelerationIPerParticle()

double[] J2Gravity.CalcAccelerationIPerParticle	(	double[]	rji,
		int	i,
		GravityState::NbodyState[]	nbodyStates
	)

Implements IForceDelegate.

CalcJerkIJPerM()

double[] J2Gravity.CalcJerkIJPerM	(	double[]	rji,
		int	i,
		int	j,
		GravityState::NbodyState[]	nbodyStates
	)

Implements IForceDelegate.
