draw_polymer_positions()

std::vector< std::vector< Utils::Vector3d > > draw_polymer_positions	(	System::System const &	system,
		int	n_polymers,
		int	beads_per_chain,
		double	bond_length,
		std::vector< Utils::Vector3d > const &	start_positions,
		double	min_distance,
		int	max_tries,

	)

Determines valid polymer positions and returns them.

Parameters

system	particle system
n_polymers	how many polymers to create
beads_per_chain	monomers per chain
bond_length	length of the bonds between two monomers
start_positions	starting positions of each polymers
min_distance	minimum distance between all particles
max_tries	how often a monomer/polymer should be reset if current position collides with a previous particle
use_bond_angle	whether to use the bond_angle argument
bond_angle	desired bond-angle to be fixed
respect_constraints	whether to respect constraints
seed	seed for RNG
