ABSTRACT	A method is described for generating boundary fitted grids to calculate the flow field across a three-dimensional cascade of blades placed radially in the axially symmetric space between the hub and casing.Successive application of a series of stretching and conformal transformation maps one-period domain of the cascade onto a box in computational space.The grid in physical space is then obtained by inverse transformation of the grid points in computational space,being an H-type grid and having a periodicity which includes the inclination of grid lines at the periodic boundary
