Advances towards Automatic Surface Domain Decomposition and Grid Generation for Overset Grids

چکیده
An algorithm for surface domain decomposition and grid generation for overset grids is described. A complex surface domain is covered by two types of grids: seam grids and block grids. Seam grids are grids used to wrap around surface crease lines and regions of high surface curvature. Block grids are grids that cover the remaining surface regions not occupied by the seam grids. The seam and block grids form a set of overlapping surface grids that cover the entire surface geometry. Given a set of seam grids, an automated method for generating the block grids is presented in this paper. Examples of seam and block grids are given for several con gurations including the V-22 tiltrotor fuselage and the X-CRV Crew Return Vehicle.

Aiaa 99-3303 Advances in Automatic Overset Grid Generation around Surface Discontinuities
A scheme is described for the automatic domain decomposition and creation of overset grids around surface discontinuities. Curves along surface discontinuities are called seam curves. The seam curves are rst automatically extracted from a multiple panel network description of the surface. Points where three or more seam curves meet are automatically identied and are called seam corners. Surface...

Making an initial tetrahedral grid for complex geometry can be a tedious and time consuming task. This paper describes a novel procedure for generation of starting tetrahedral cells using hexahedral block topology. Hexahedral blocks are arranged around an aerodynamic body to form a flow domain. Each of the hexahedral blocks is then decomposed into six tetrahedral elements to obtain an initial t...

The use of overset grids in CFD started more than two decades ago, and has achieved tremendous success in handling complex geometries. In particular, overset grids have the advantage of avoiding grid remeshing when dealing with moving boundary flow problems. Traditionally overset grids were mainly used with structured grids to simplify the grid generation process, because a complex computationa...
متن کاملAutomation of Hole-Cutting for Overset Grids Using the X-rays Approach
Overset grids resolve complicated geometries by creating high quality structured grids that are independently built for each component. This simplifies the process of grid generation, but domain connectivity must be performed so that adjacent grids share information. Shortcomings of the current X-rays method for the hole-cutting step of domain connectivity were explored to automate the X-rays a...
