Custom force. Sample code to show how to make a custom force. To use this set the GE force delegate to custom and attach this script to the object holding the GravityEngine.

Member Function Documentation

CalcAccelerationIJPerM()

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

Implements IForceDelegate.

CalcJerkIJPerM()

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

Implements IForceDelegate.

CalcPseudoForce()

double CustomForce.CalcPseudoForce	(	double	r_sep,
		int	i,
		int	j,
		GravityState::NbodyState[]	nbodyStates
	)

acceleration = a * ln(b * r)

Returns

The accel.

Parameters

r_sep	R sep. The distance between the bodies
i	index of one pair in force (i < j)
j	index of second pair in force
