MORPHING METHOD FOR STRUCTURAL SHAPE AND ITS COMPUTER PROGRAM AND COMPUTER READABLE STORAGE MEDIUM

PROBLEM TO BE SOLVED: To easily prevent any unrealistic deformed shape from being calculated when acquiring the FEM (finite element method) model of a structure to be analyzed by using the FEM model of a prototype structure. SOLUTION: A plurality of corresponding reference points are set at the first point of view for the visible outline of a new type of vehicle and the FEM model of an already existing vehicle, and a mesh model included in the FEM model of the already existing vehicle is changed to the visible outline of the new type of vehicle based on the corresponding relation of those reference points and the mesh model, and accessories information include in the FEM model of the already existing vehicle and the associated state are redefined for the deformed mesh model according to the movement so that the FEM model of the new type of vehicle can be calculated. Prior to this process, since the cross-section shape of a member (for example, A pillar) extended to a longitudinal direction at the first pint of view is difficult for a user to recognize, the user is able to set the deformed shape of the member according to a set picture from which the cross-section shape of the member based on the second pint of view which is different from the first point of view is easy for the user to recognize.
