Member Function Documentation

Eigen::MatrixXd NuTo::ParticleCreator::CreateSpheresInSpecimen	(	const double	rRelParticleVolume,
		const Eigen::MatrixXd &	rGradingCurve,
		const double	rRelativeDistance,
		const double	rAbsoluteDistance,
		const int	rSeed,
		const Eigen::MatrixXd &	rSpheresBoundary
	)		const

creates randomly distributed, non-overlapping particles

Parameters

rRelParticleVolume	percentage of particle volume inside the box
rGradingCurve	matrix with each line min_diameter, max_diameter, volume percentage of that sieve size
rRelativeDistance	scaling factor to increase the diameter when inserting the sphere to ensure a minimum distance
rAbsoluteDistance	scaling value to increase the diameter when inserting the sphere to ensure a minimum distance
rSeed	seed for the random number generator
rSpheresBoundary	particles simulated on the boundary e.g. created with CreateSpheresOnBoxBoundary (they do not contribute to the grading curve)

void NuTo::ParticleCreator::PerformPlacePhase	(	Eigen::MatrixXd &	rParticles,
		const double	rRelativeDistance,
		const double	rAbsoluteDistance
	)		const

performs the "place"-of the "take-and-place" algorithm

Parameters

rParticles matrix with randomly distributed, non-overlapping particles

Eigen::MatrixXd NuTo::ParticleCreator::PerformTakePhase	(	const Eigen::MatrixXd &	rGradingCurve,
		const Eigen::MatrixXd &	rSpheresBoundary,
		const double	rRelParticleVolume
	)		const

performs the "take"-of the "take-and-place" algorithm
