I'm asking because of this question about network simulation, which currently has two votes to close as off-topic. I would classify it as "computational science for computer science." Certainly it is science; the software is used in many publications of IEEE and similar. And it is clearly computational. The FAQ currently says this site is for computational methods used in technical disciplines.
So it seems to fit the criteria of our site, although I don't know if we have any users who can answer it. Should it be on-topic?
