    "abstract": "We present a versatile high-level programming-language implementation of\nnonlinear topology optimization. Our implementation is based on the commercial\nsoftware package Femlab, and it allows a wide range of optimization objectives\nto be dealt with easily. We exemplify our method by studies of steady-state\nNavier-Stokes flow problems, thus extending the work by Borrvall and Petersson\non topology optimization of fluids in Stokes flow [Int. J. Num. Meth. Fluids\n2003; 41:77--107]. We analyze the physical aspects of the solutions and how\nthey are affected by different parameters of the optimization algorithm. A\ncomplete example of our implementation is included as Femlab code in an\nappendix.",
