“…Each algorithm can then be constructed using common building blocks such as convergence acceleration schemes, predictors, and interpolation methods. The building blocks as well as software tools for the data transfer from one solver to another have been implemented in the C++ library comana (see [122]), which will be introduced in the subsequent part (Coupling software).…”

The present work is concerned with the partitioned solution of the multifeld problem arising from a hierarchical modeling approach to cardiovascular ﬂuid-structure interaction. Different strategies to couple the participating feld solvers are investigated in detail. This includes staggered and parallel coupling algorithms as well as different methods for convergence acceleration, spatial interpolation and temporal extrapolation of coupling quantities. In the developed modeling and simulation approach, a fully resolved model of a segment of the arterial network is coupled to reduced order models in order to account for the inﬂuence of the surrounding. There is experimental evidence that hemodynamic quantities such as the wall shear stress promote the progression cardiovascular disease. Cardiovascular FSI simulations, that can predict these quantities, are therefore of great interest and can aid in surgical planning and optimization of anastomoses shapes and graft materials.

Crew transfer vessels are a fast and cost-effective means of transportation to bring service personnel and technical equipment to an offshore wind turbine. The landing manoeuvre of such service vessels is a complex coupled process involving the ship's motion in the seaway and the frictional contact between the fender and the boat landing. With the help of numerical simulations, we aim to identify the limit conditions under which a safe crew transfer can still be ensured, and to investigate innovative transfer concepts which serve to avoid severe accidents. In our research, we draw on a partitioned solution strategy which has already been successfully applied to other sophisticated multi-field phenomena and which allows to reuse specialised existing solvers for the solution of the involved subproblems.

“…Simulation of structural dynamics is performed by means of AdhoC, a finite element method (FEM) developed at the Institute for Ship Structural Design and Analysis (SKF), which offers the use of high order shape functions. The coupling between both domains is managed by the software comana [2], which is also developed at the SKF. comana is a C++ environment for the simulation of strongly coupled multifield problems.…”

Regarding new propeller materials and designs, vibrations and large deformations are becoming increasingly relevant. Therefore, simulation methods need to be developed which take into account the interaction of fluid and structure while retaining a computational effort suitable for the design stage. In the approach presented here, the fluid mechanical subproblem is solved by means of the software panMARE, which is based on the potential theory. The structural-mechanical subproblem is engaged using different structural solvers as well as modelling approaches. Information exchange between the subproblems is managed by the software comana.
