PURPOSE:To execute the multiplex nodal point sticking and to automate the setting of a nodal point number by inputting the data to show the mutual linking relation of plural divided and inputted areas into a computer together with a plane-shaped data beforehand and correcting a nodal point number. CONSTITUTION:Plane-shaped data 2 of plural areas dividing a three-dimensional curved surface from a computer terminal 1 and the coupling relation data 3 of the plane showing the mutual relation of the area are inputted to a coordinate arithmetic part 4. The coordinate arithmetic part 4 is composed of a lattice coordinate calculating part 4a and a nodal point number setting part 4b. Based on the plane data, the lattice coordinate calculating part 4 obtains a segmenting polynomial to specify a three-dimensional curved surface and lattice-divides the curved surface in accordance with the number of division. The nodal point number setting part 4b sets the nodal point number to a generated lattice. The appearance of the generated lattice can be confirmed by outputting a graphic to a CRT terminal 5. A boundary element method numeric value analyzing program 7 outputs the three-dimensional coordinate data 6 of the usable form.
