In this work, the Modified Iterative Group Implicit Algorithm (MIGI), a domain-by-domain parallel solution method is extended for nonlinear applications. For the nonlinear case, while MIGI iterates to find compatible and equilibrating interface forces between the subdomains, a global nonlinear iteration is also performed. The integration of these two iterations is investigated. More specifically, the two iterations may be combined and performed in a single process loop or they may be isolated. It is found that the efficiency of the procedure resulting from the isolation of the iterations is superior than the alternative. The developed procedure has been tested via numerical examples. A 20-story model building considering material and geometric nonlinearities under earthquake loading has been simulated. Excellent accuracy in the solution and significant speedup values have been obtained from the simulations, which were performed on an IBM-SP parallel machine.
