Simulations with solution based mesh adaptation for fluid structure interactions

Simulations of multi-physics systems are time consuming and therefore acceleration techniques are commonly used. The current research focuses on the application of solution based mesh adaptation to fluid structure interaction (FSI) computations. The FSI-solver used in this work is a partitioned solver that consists of a RANS solver for the flow and a rigid body solver for the structure. The aim is to assess the gain in efficiency when using solution based mesh adaptation in combination with FSI. Thereby, the number of time steps between successive adaptations and the number of adaptation steps per adaptation are considered. Preliminary results indicate the potential of the method, since flow features are resolved more detailed with the same number of cells.
