On MPCCI as a coupling library for Fluid-Structure Interaction with CFX. One major simplification made when calculating physical behaviour is to take one field into account. While this may often be sufficient, some engineering problems require to consider two or more fields. For a flexible structure submerged in a fluid, the interaction of the fluid with the structure may be the driving mechanism characterising its behaviour. For the individual disciplines sophisticated solvers exists. Different solution methods for various flow problems have been developed. Various numerical methods and code implementations have been used to increase the quality of the results. In order to find a common basis of comparison, a set of benchmark problems have been defined. In view of the results of previous numerical tests a commercial robust fluid solver ANSYS-CFX was chosen. MpCCI is a communication library to which ANSYS-CFX provides an interface. Goal of this thesis was to assess this interface such that a structural solver could be connected to this interface. Therefore, the major steps had to be followed. First to assess the fluid solver by calculating a cylinder submerged in a fluid benchmark. Second to write a dummy structural code providing an interface to MpCCI and finally to couple the both codes such that an algorithmic coupling was possible.     «
