✦ Synopsis

This paper describes the three-dimensional elliptic grid generation. The two-dimensional approach for the control functions obtained by modifying the Thomas -Middlecoff method is applied on the planes perpendicular to the main flow direction co-ordinate, which is assumed to be the function of only one corresponding co-ordinate in the computational domain. The grid orthogonality is improved by about 40 per cent compared with that of the algebraic initial grid.
