Semi-Automated Approach To Shape Optimal Design Of Planar Structures, Gurinder Pal Singh

Theses

This paper presents a general algorithm, using IDEAS programmability features to integrate different phases of shape optimization process. The present work is mainly concentrated on planar structures, defined by thin or shell finite elements. Interactive programs are generated to convert input data to geometric models, to define mesh areas, to generate finite element mesh and to execute adaptive mesh refinement techniques. The importance of automated mesh generation and refinement is highlighted and various optimization methods are considered. Further, a special attention is given to integration issues of shape optimization capabilities into CAD environment. To demonstrate the developed algorithm, an automotive …
