Volume based discretization schemes (finite elements and finite differences) can only be used to deal with boundary value problems posed on unbounded domains, when artificial truncation of the domain is employed. At the new artificial boundary boundary conditions have to employed that represent the impact of the neglected exterior part of the domain. Various approaches to the construction of such boundary conditions have been devised:
