solve()

void coUniTracer::solve	(	const float *	yini,
		std::vector< coUniState > &	solution,
		float	eps_rel,
		float	max_length = 2.0,
		float	vel_factor = 0.005,
		int	ts = 1
	)		const

solve is a driver using a RK-stepper, after compkletion you get the solution in parameter solution yini is an array of three float with the initial point, solution is the output streamline eps_rel is the relative error used by the stepper length_factor is the streamline maximal length relative to the model characteristic dimension and vel_factor is used to specified when the integration is interrupted for too low speeds (a speed is too low when smaller than this factor multiplied by the highest speed in the model).

stop()

bool coUniTracer::stop ( float  factor, const std::vector< coUniState > &  solu  ) const
