Summary

A parallel approach for the optimization of fluid-structure problems with a direct coupling via the Message-Passing-Interface (MPI) is presented. For the fluid-structure interaction an implicit partitioned solution approach with a finite-volume flow solver and a finite-element structural solver is employed. For the optimization a sequential quadratic programming approach is used. The MPI coupling is realized by a subcommunicator concept which integrates the optimization algorithm and the fluid and structural solvers. The performance of the direct MPI coupling approach is analyzed by comparing the runtimes for the different components of the integrated procedure, where also the influences of the grid resolution and the numbers of processors are taken into account. Furthermore, a comparison with a server-based coupling approach employing the coupling library MpCCI is presented. Finally, the proposed approach is applied to a representative steady fluid-structure interaction optimization problem.
