Best Practices in Overset Grid Generation [PDF]
32nd AIAA Fluid Dynamics Conference and Exhibit, 2002 Grid generation for overset grids on complex geometry can be divided into four main steps: geometry processing, surface grid generation, volume grid generation and domain connectivity. For each of these steps, the procedures currently practiced by experienced users are described. Typical problems encountered are also highlighted and discussed.

Deformable Overset Grid for Unsteady Aerodynamic Simulation
54th AIAA Aerospace Sciences Meeting, 2016 A deformable overset grid method was proposed to simulate the unsteady aerodynamic problems with multiple flexible moving bodies. This method uses an unstructured overset grid locally coupled with mesh deformation to achieve both robustness and efficiency. The overset grid hierarchically organizes the sub-grids into CLUSTERs and LAYERs, allowing for

Implementation and verification of an explicit overset grid method [PDF]
, 2018 This paper presents an initial implementation of the overset method in the solver ReFRESCO. The DCI (Domain Connectivity Information) is computed by the external library Suggar++ and the coupling between meshes is done explicitly. Manufactured solutions and analytical solutions are used in order to quantitatively assess the discretisation errors.

A user`s guide for BREAKUP: A computer code for parallelizing the overset grid approach [PDF]
, 1998 In this user`s guide, details for running BREAKUP are discussed. BREAKUP allows the widely used overset grid method to be run in a parallel computer environment to achieve faster run times for computational field simulations over complex geometries.

Transition prediction for high-lift flows using a crossflow-extended RANS transition model with overset grid [PDF]
AIP AdvancesHigh-lift flow simulations remain challenging for Reynolds-averaged Navier–Stokes methods, largely due to the coexistence of laminar separation bubbles, boundary-layer transition, wake/shear-layer interactions, and three-dimensional effects. In this work,

On automating domain connectivity for overset grids [PDF]
33rd Aerospace Sciences Meeting and Exhibit, 1995 An alternative method for domain connectivity among systems of overset grids is presented. Reference uniform Cartesian systems of points are used to achieve highly efficient domain connectivity, and form the basis for a future fully automated system.
