A domain decomposition approach for the transient analysis of arbitrary three‐dimensional soil–structure interaction problems is presented. The coupling of the subdomains is performed in an iterative manner. For this purpose, a sequential as well as a parallel interface relaxation algorithm have been developed, where the coupling iterations are performed very effectively together with the iterations which are required to solve the nonlinear FEM system of equations.
