Abstract:
The MCF software package devoted to solving coupled problems of hydroelasticity
is described. Various ways of solving the problems with strong and weak coupling
are considered. Iterative methods are chosen due to their simplicity in
implementation and scaling. The coupling of the OpenFOAM software package (turbulent
motion of incompressible, weakly compressible, and compressible fluids) with
the two models of structural dynamics based on the finite-volume method (OpenFOAM)
and on the modal approach (UZOR) is discussed. The performance analysis of the
developed software using the clusters of the Taganrog Institute of Technology
and the State University of Chelyabinsk is given.
