Detailed Description

A class representing the contact forces and moments arising from a contact interaction.

This class stores both local and global representations of the contact forces and moments, as well as separate components along the normal and tangential directions. The local representation includes the contact force and moment components computed at each point of contact, while the global representation includes the summed contact forces and moments acting on all points of contact.
