In order to accurately simulate the complex flow phenomena surrounding wind turbines and turbomachinery, it is crucial to perform coupled fluid-structure interaction (FSI) simulations to asses the aerodynamic loads and the aeroelastic behaviour. Thus, it is essential to have high-order, accurate and cost-effective methods to analyze FSI problems to improve the efficiency of existing turbine designs or propose new typologies or configurations. However, accurately simulating the relative motion of the blades can be challenging, especially while keeping computational costs low. In this work, we propose the use of a high-order Finite Volume method based on Mean Preserving Moving Least Squares (FV-MP-MLS) in a Chimera/overset grid framework, to account for the movements of the solid bodies. We thoroughly tested the performance and efficiency of the methodology by solving several benchmark problems.
