Abstract

Abstract:

A general generation method is presented for the 3 D multiply blocked structure grid of a complex configuration flying body.The structure grids can be generated by decomposing the domain into any number of contiguous blocks,and each physics region can be considered to have been transformed to a rectangular computational region on which the curvilinear coordinates are the independent variables.Thus the generated grid is not too skew or unregular.Effect of control functions on grid generation is discussed.The given examples showed that the method may deal with arbitrary complex 3 D domains with the multi blocked structure technique.

Key words: flight vehicles, elliptic equations, grids

CLC Number:

V211. 3
