Abstract:
A designing system conducting a structure analysis of an original model by modifying the shape of the model, comprising:a meshing unit meshing the original model; a child edge generation and display unit generating a child edge, which is the same in shape and location with a parent edge representing an edge of the original model, and displaying the child edge on a display screen; a modification unit modifying the shape of the displayed child edge according to an interactive input made by an operator; a correspondence unit projecting nodes of the parent edge, which result from the meshing performed by the meshing unit, onto the modified child edge and correlating coordinates of the nodes with those of the corresponding projected points respectively to obtain a correspondence relationship between the parent edge and the modified child edge; and a structure analysis unit conducting a structure analysis of the model, of which the shape is modified, in a manner as specified by the correspondence relationship obtained by the correspondence unit.
