The focus is on the temporal coupling between fluid and structure dynamics.
The relative velocity between fluid and structure is considered to establish the hydrodynamic pressure (radiation and impact).
Additional forces developed by motion dependent interaction effects between fluid and structure are estimated by the help of finite-difference-software.
It is concluded that added mass effect and damping due to the degree of coupling between fluid and structure plays a vital role in whipping response prediction.
Then, the finite element method is applied to the governing equations obtained, with the aid of an improved moving mesh technique implemented by the modified spring analogy to deal with the coupling between fluid and structure surfaces.
The results of the present work indicate that there is a strong coupling between fluid and structure, and thus the fluid and structure influence each other in a particular manner.

In the modeling of fluid structure interaction, mode truncation and inertial coupling between fluid and structures are applied to sufficiently reduce model order.
The property behavior of melts and fluids in hydrous silicate systems at the high temperatures and pressures can be traced to the relationships between fluid and melt structure and their properties.
Two-way coupling between the fluid and structure is considered in all the examples.
Our method features an unstructured dynamic mesh capable of modeling complicated geometries, an arbitrary Lagrangian Eulerian framework that allows for large displacements of the moving fluid domain, monolithic coupling between the fluid and structure equations, and fully implicit time discretization.
In contrast with traditional loosely-coupled schemes, no iterations are necessary between the fluid and structure sub-problems; this is due to the fact that our novel splitting strategy uses the "added mass effect" to stabilize rather than to destabilize the numerical algorithm.
