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 overlapintersect 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 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'''.
