This section describes all of the global parameters that affect simulation. All of these parameters are set by the parameter command with parameter key=value ....
Simulation parameters:
Convergence parameters:
Set the threshold for maximum delta in position for considering convergence.
Set the threshold for maximum delta in velocity for considering convergence.
Set the threshold for maximum delta in energy for considering convergence.
Physics parameters:
Viscous damping coefficient that applies a linearly dependent force in the opposite direction of the velocity vector.
Temperature is used to randomly perturb the position of all objects after each iteration. Random perturbation is means by which annealing is simulated.
Object proximity is modeled as spring repulsion. repulsion_coeff is the repulsion spring coefficient for a compressed spring, which models the collision of soft objects. repulsion_constant is a constant additive force term for the spring that is compressed to model the hardness of the boundary.
Gravity parameters:
The linear spring coefficient for gravity wells in the x,y,z direction.
The constant force term for gravity wells in the x,y,z directions. Setting this to non-zero helps attract objects closer to the well.
Feedback parameters:
