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.

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.

An analysis of performance enhancement techniques for overset grid applications [PDF]
Proceedings International Parallel and Distributed Processing Symposium, 2004 The overset grid methodology has significantly reduced time-to-solution of high-fidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process resolves the geometrical complexity of the problem domain by using separately generated but overlapping structured discretization grids that periodically ...
