Abstract
A coupled simulation for the computational fluid dynamics (CFD) and the computational. structure dynamics (CSD) has been performed on a heterogeneous parallel computer cluster. Tlie main solvers for CFD and CSD and the grid generator are executed being distributed to different parallel computers, which are connected by a network. The fluid and the structure dynamics are, coupled by exchanging the boundary data between the fluid and: the structure domains through the network. The data communication among processes oti a parallel computer and on different parallel computers is realized by the heterogeneous communication library, Stampi. In this paper, the procedure of the distributed parallel computing for the fluid/structure coupled simulation will be presented, and it will be shown that the distributed parallel computing has the greater advantage of increasing the total performance than parallel computing on a single parallel computer.
