A new grid generation method is proposed. The geometrical method has been modified to produce the present implicit geometrical method. An iteration to modify initial grid is regarded as time integration, and an explicit time differencing operator is replaced by an implicit Padè time differencing. Four requirements, i. e. orthogonality, smoothing, clustering, and minimum spacing are imposed to obtain a convergent grid. 2D grids are shown as examples and extension to 3D to generate grids around a practical ship hull form is explained.
