An Overset Grid Method for Fluid-Structure Interaction
World Journal of Mechanics, 2014 An overset grid methodology is developed for the fully coupled analysis of fluid-structure interaction (FSI) problems. The overset grid approach alleviates some of the computational geometry difficulties traditionally associated with Arbitrary-Lagrangian-

Robust and Scalable Overset Grid Assembly for Partitioned Unstructured Meshes
51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013determine the cell that contains a given point is the core procedure necessary for accomplishing this task. Donor search is particularly challenging for partitioned unstructured meshes because of the complex geometry that is often created at the boundaries of each mesh-block during partitioning.

Resolution Appropriate Overset Grid Assembly for Structured and Unstructured Grids
16th AIAA Computational Fluid Dynamics Conference, 2003The assembly of an overset grid system requires two different resolution scales to perform the required holecutting and donor cell location. The assembly of nearbody grids, with overlapping surface grids and possible viscous layers, requires high-resolution and special procedures to produce an accurate assembly.

Analysis of Non-Conservative Interpolation Techniques in Overset Grid Finite-Volume Methods
Computers and Fluids, 2017 This paper reports on the challenges of using an overset grid approach when simulating incompressible flows with a cell-centred finite-volume solver. The focal point is on the grid coupling approach.

The Overset (Chimera) Grid approach has many practical benefits for unsteady moving grid simulations. However, an inherent requirement and challenge is the need to establish the inter-grid communication and donor-receiver pairs where the solution must be exchanged between overlapping grids via a process formally known as overset grid assembly ...
