  • Approaches to accommodate remeshing in shape optimization 
    Wilke, Daniel Nicolas (University of Pretoria, 2010)
    This study proposes novel optimization methodologies for the optimization of problems that reveal non-physical step discontinuities. More specifically, it is proposed to use gradient-only techniques that do not use any ...
  • Relaxed error control in shape optimization that utilizes remeshing 
    Wilke, Daniel Nicolas; Kok, Schalk; Groenwold, Albert A. (Wiley-Blackwell, 2013-04)
    Shape optimization strategies based on error indicators usually require strict error control for every computed design during the optimization run. The strict error control serves two purposes. Firstly, it allows for the ...
