In overlapping ___domain decomposition methods, the subdomains overlap by more than the interface. Overlapping ___domain decomposition methods include the [[Schwarz alternating method]] and the [[additive Schwarz method]].

In non-overlapping methods, the subdomains overlap only on their interface. In primal methods, such as [[Balancing ___domain decomposition]] and [[BDDC]], the continuity of the solution across subdomain interface is enforced by representing the value of the solution by on all neighboring subdomains by the same unknown. In dual methods, such as [[FETI]], the continuity of the solution across the subdomain interface is enforced by [[Lagrange multiplier]]s. The [[FETI-DP]] method is hybrid between a dual and a primal method.

Non-overlapping ___domain decomposition methods are also called '''iterative substructuring methods'''.
