PROJECT DESCRIPTION: The accurate and conservative treatment of load transfer across the fluid/structure interface plays a key role in the accuracy of the overall aeroelastic problem. this project aims at the development and assessment of new load transfer and temporal coupling schemes for transient fluid/structure interaction problems characterized by non-matching interface discretizations. in particular, we investigate a novel load transfer scheme, referred to as the common refinement scheme, which provides substantial improvements in the accuracy of the load transfer scheme compared with load transfer schemes available in the literature.
