In this study, orthogonal and structured grid generation around a cylinder is described by using
potential functions. In this method, the orthogonality of and n functions are used for grid generation. First,
coordinates of points are given by using the algebraic method on cylinder boundaries and then, according to
known potential functions in terms of x and y values in the external flow around a cylinder, coordinates of other
network's points are calculated through solving a system of two nonlinear equations with two unknowns.
Iteration methods are used for solving this system of equations. The generated grid besides orthogonal property
has small distances on the surface of cylinder and gradually as it goes farther away from the cylinder, the
distance between nodes rises. This kind of grid can be useful in solving the flow field around a cylinder.
Key words: Complex potential function, grid generation, orthogonal grid, , , ,
