Interface Module

Overview

freud.interface.Interface

Measures the interface between two sets of points.

Details

The freud.interface module contains functions to measure the interface between sets of points.

class freud.interface.Interface

Bases: freud.locality._PairCompute

Measures the interface between two sets of points.

compute(self, system, query_points, neighbors=None)

Compute the particles at the interface between two sets of points.

Parameters

• system – Any object that is a valid argument to freud.locality.NeighborQuery.from_system.

• query_points ((\(N_{query\_points}\), 3) numpy.ndarray, optional) – Second set of points (in addition to the system points) to calculate the interface.

• neighbors (freud.locality.NeighborList or dict, optional) – Either a NeighborList of neighbor pairs to use in the calculation, or a dictionary of query arguments (Default value: None).

default_query_args
