MeanSquaredDisplacement

class MeanSquaredDisplacement : public feasst::Analyze

Compute the mean squared displacement of the sites over number of trials. Note that this is the traditional approach, not the more efficient order-n approach as described in Frenkel and Smit, Section 4.4.1. New origins are stored every fixed number of updates. Assume the number of particles does not change.

Arguments

• updates_per_origin: set the number of updates until creation of a new origin (default: 1000).

• group_index: group_index associated with configuration (default: 0).

• Stepper arguments.
