Computational Fluid Dynamics-CFD is the numerical study of the behavior of systems involving fluid flow, heat transfer and other related physical processes. Computational Structural Dynamics involves the study of the dynamic behavior of structures.A wide range of physical phenomena involves both fluid dynamics and structural dynamics that influence each other. Typical Fluid-Structure Interaction involves fluid flow affecting the structural response and vice versa. In this thesis work, fluid-structure interaction problems are studied using various remeshing conditions. Further to this study codes are written to reduce the lead-time during analysis, minimal use of resources and to improve new tools for remeshing
