We present a new grid movement strategy, tested for a generic fluid-structure interaction (FSI) test case. The test case describes a flat plate with a prescribed rotational movement in a turbulent channel flow. The transient turbulent flow field is calculated with a low-Re RANS model. To account for the deforming fluid domain two different grid movement methods are compared. Using transfinite interpolation with a grid-point distribution fitted to the stationary starting conditions as grid moving method leads to errors for the drag-coefficient. By employing a normalized wall distance adaptive method it is possible to fulfill the near-wall resolution requirements within every time step and, to thereby, get more accurate results. The parallelization is achieved by domain decomposition and is evaluated using a strong scaling experiment.
