Detailed Description

An abstract class representing a collision solver for a particle and a wall.

This class provides an interface for detecting and resolving collisions between a particle and a wall, and includes methods for initializing and updating the contact geometries associated with each collision. Subclasses are expected to implement the core collision detection and resolution logic.
