| Abstract: | A quadratic shape function is used to represent the boundary curved line or surface by referring to the method developed by Zienkiewicz-Lin Taitau so that two-dimensional automatic mesh generation can be extended to three-dimensional curved surface and body. A program (GMG) has been worked out, which has proved useful in the optimum design for hydraulic turbine parts. |
