The provided geometry is used in the publication "Numerical simulation of endovascular treatment options for cerebral aneurysms" authored by Martin Frank, Fabian Holzberger, Medeea Horvat, Jan Kirschke, Matthias Mayr, Markus Muhr, Natalia Nebulishvili, Alexander Popp, Julian Schwarting and Barbara Wohlmuth. Starting from the original dataset no. C0074b from the Aneurisk archive of aneurysm geometries [http://ecm2.mathcs.emory.edu/aneuriskweb/index], this geometry is the result of the pre-processing tool chain outlined in Section 3 of the manuscript to modify the input geometry with the goal of subsequent flow simulations. This geometry can be found in Figures 2, 3 and 7 of the manuscript. Most importantly, this geometry serves as the basis for the numerical experiments with the lattice Boltzmann method (Figures 14, 15, and 16) in Section 6.2 of the mansucript. The file is provided in the *.obj format including the described coloring of in- and outflow boundaries. The file can be inspected and converted to different file-formats, e.g. using the software meshlab [https://www.meshlab.net/].
