We recently got a question on Physics.SE about how to properly simulate multi-body collisions that occur within a time step. The OP says he was directed away from Stack Overflow, but it seems off topic for Physics.
The next obvious candidate for where this question should go is this site, but the question is about a pretty simple programming problem. As much as we've decided that "heavy computation" is not the optimal description for this site, it seems that that wording was chosen to suggest that questions like this one about collisions are not what this site is about. Is that correct?
And the main question: Are simple simulation questions like this on topic here?
(It's likely that this particular question is appropriate for Stack Overflow and will stay there. But I'm posting this because I think it will be good to know what our position is on this kind of question.)
