Intergrid-Boundary Definition Method for Overset Unstructured Grid Approach

AIAA Journal, 1999
The use of the overset concept for the unstructured grid method is relatively unexplored. However, the overset approach can extend the applicability of the unstructured grid method for real engineering problems without much need for code development. The multiple moving-body problem is one of those applications.

On the need for higher order interpolation with overset grid methods [PDF]

, 2019
Overset methods, by overlapping several grids, allow large and arbitrary motion of bodies. First developed for the aerospace industry (Benek et al., 1985), it is now used for a wider range of applications like maritime ones (Carrica et al., 2013). At the fringes of each grid, the coupling is done by interpolating field variables.

A weighted bidirectional interpolation strategy for an overset grid method

A weighted bidirectional interpolation strategy has been developed for overset grid methods to accurately and efficiently simulate incompressible flows involving complex geometries or moving boundaries. Inspired by the DRAGON grid approach, special attention is given to the arrangement of component grids and the data transfer between them.

Overset-Grid Method with Smooth Orbital Partitioning for Molecular Scattering Calculations

Journal of Chemical Theory and Computation
To solve molecular photoionization and electron scattering problems, we use an overset-grid representation of electronic continuum functions, which has an extended central spherical grid that overlaps small spherical grids (subgrids) centered on each atom of a polyatomic molecule.

A parallel hybrid overset grid assembly method and its application

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering
The 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
