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.

A parallel hybrid overset grid assembly method and its application
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace EngineeringThe overset grid method can effectively solve the complex flow problem of large-scale relative motion, but it is difficult to guarantee efficiency and accuracy of the overset grids with over 10 million scale and dozens of components. Based on a hybrid overset grid system that supports unstructured, Cartesian, and polyhedral meshes, an automated and MPI

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 ...
