Interesting question! The function doesn't currently allow that, it uses the same sequence of random numbers every time -- by design: This way, if you run your program twice in a row, it'll produce the same result. But it wouldn't be very difficult to change that. The function is here: https://github.com/dealii/dealii/blob/master/source/grid/grid_tools.cc#L1013-L1244 The random number generator is initialized in line 1099. It wouldn't be very difficult to add an argument to the function that acts as a random seed and is used in that line to seed the boost::random::mt19937 generator. Want to give this a try and implement such a change? We'd of course be very happy to take a patch!

[deal.II] Using different random seed when distorting a triangulation
Hello everyone. I would like to apply many random distortions to a triangulation. However, the function GridTools::distort_random seems to produce always the same distortion. Is there a way to use different seeds in order to generate always different distortions? It seems that it's not possible through the interface of GridTools::distort_random but I wonder if there is another way to do it, since this seems to me a very basic feature for the users of this function.

[deal.II] Blog post about how we develop deal.II
Well, not really about how *we* develop deal.II -- but at least about my approach in general to developing software: https://bssw.io/blog_posts/making-myself-better-what-craftspeople-can-teach-us-about-software I think that what I describe is how a lot of good programmers think about their craft. If you're still learning how to be a programmer, this might be of interest to you. See many of you tomorrow for the deal.II workshop!
