A new interactive grid generation program is developed for 2-D and 3-D multi-block structured grids. Present program can generate and redistribute grid points on arbitrary curves. It also provides the generation of 2-D field grid system with algebraic or elliptic partial differential equation method. The surface and field grid systems of the 3-D configurations are generated with algebraic method. Each object can be modified through transformation or reused to generate new one. All the working procedure can be stored and replayed at any time. The graphical user interface (GUI) has been implemented with OSF/Motif and X toolkit for convenient user environment and the graphics language is OpenGL for visualization of the 3-D objects.
