void dsim_ideal_spring::initialization_complete

(

)

[virtual]

Look up the target now that model initialization is complete. If no target is found, use the parent object. Set the target object's position as cointegrated.

Reimplemented from dsim_model.

void dsim_ideal_spring::initialize_data

(

)

[virtual]

Create the target for the mass that will be connected to this spring. This target must accept the 'apply_force' message. Also create the two parameters: the spring constant "k" and a vector for the location of the based of the spring.

Reimplemented from dsim_model.

void dsim_ideal_spring::rhs	(	double	t,
		double	jd
	)		[virtual]

Dynamics. Compute the spring force and send the 'apply_force' message to the target. The force is equal to the spring constant k times the difference between the spring base position and the target position .

Parameters:

t	Elapsed time, unused
jd	Julian date, unused

Reimplemented from dsim_model.
