wall¶

Walls define an oriented surface in space. Walls exist only in the primary box image and are not replicated across the periodic boundary conditions. Points on one side of the surface have a positive signed distance to that surface, and points on the other side have a negative signed distance.

Define individual walls with Cylinder, Plane, and Sphere. Create lists of these WallGeometry objects to describe more complex geometries. Use walls to confine particles to specific regions of space in HPMC and MD simulations.
