Function Documentation

error_rosenbrock()

void error_rosenbrock	(	MbsData *	mbs_data,
		MbsDirdyn *	dd,
		int	err
	)

If an error occurs during time integration, this function prints the error message and call finish_rosenbrock.

Parameters

mbs_data	The computed MBS structure
mbs_dd	The associated MbsDirdyn structure
err	The error number

finish_rosenbrock()

void finish_rosenbrock	(	MbsData *	mbs_data,
		MbsDirdyn *	mbs_dd
	)

Finalize and clear memory allocated for Rosenbrock integrator.

Parameters

mbs_data	The computed MBS structure
mbs_dd	The associated MbsDirdyn structure

initialize_rosenbrock()

void initialize_rosenbrock	(	MbsData *	mbs_data,
		MbsDirdyn *	mbs_dd
	)

Initialize all needed fields in MbsDirdyn for Rosenbrock integrator.

Parameters

mbs_data	The computed MBS structure
mbs_dd	The associated MbsDirdyn structure

loop_rosenbrock()

int loop_rosenbrock	(	double	t0,
		double	tf,
		MbsData *	mbs_data,
		MbsDirdyn *	mbs_dd
	)

Integrate the motion from t0 to tf.

Parameters

t0	The initial time
tf	The final time
mbs_data	The computed MBS structure
mbs_dd	The associated MbsDirdyn structure

Returns

Error status, <0 in case of failure.
