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. Copyright © 2000 John Wiley & Sons, Ltd.
