| Abstract(E) | To achieve global shape optimization using isogeometric analysis, we develop a scheme to repeat optimization and change the number of control points of the structure automatically. By updating the number of control points and search area step by step, the design space can be widely explored while avoiding shape breakdown. In the second report, the objective is to achieve more robust shape optimization that is independent of the initial geometry. The effectiveness of the proposed method is assessed by expanding the search domain and comparing the results derived from different initial geometries. |
