 - Design optimization with Navier-Stokes flow: The pipe bend (`navier_stokes/pipe_bend`) and rugby ball (`navier_stokes/rugby_ball`) problems which are considered in Section 4.4 of the paper.
 
 
-In each of the directories, there is a `main.py` file, which can be used to run the code. This file runs the entire benchmark, consisting of the so-called sphere combination, convex combination, gradient descent and BFGS methods.
+In each of the directories, there is a `main.py` file, which can be used to run the code. This file runs the entire benchmark, consisting of the so-called sphere combination, convex combination, gradient descent and BFGS methods, as presented in [Quasi-Newton Methods for Topology Optimization Using a Level-Set Method](arxiv_tba).
 
-Each problem is solved with the aggressive space mapping method for shape optimization presented in [Quasi-Newton Methods for Topology Optimization Using a Level-Set Method](arxiv_tba).

-In the `visualization` directory, the file `visualization.py` generates the plots used in the paper. The repository is already initialized with the solutions obtained for the numerical examples in the paper, so that this can be run directly.
