WebbThis boundary definition is actually a shortcut to the more general FEniCS concept SubDomain. A SubDomain is a class which defines a region in space (a subdomain) in terms of a member function inside which returns True for points that belong to the subdomain and False for points that don’t belong to the subdomain.

However, it still remains somewhat vague as to what exactly BC are, how they can or even should be explored, and why their understanding matters.
