Re: [deal.II] Using different random seed when distorting a triangulation

know how to fix this problem, because it complains about a format error which seems to actually not be there in my code and only shows up in the check. I'd appreciate it if you could tell me the reason for this problem. David. On Tuesday, 26 May 2020 at 05:40:57 UTC+2 Wolfgang Bangerth

Re: [deal.II] Mesh-induced elastic anisotropy and distorting the quad. points as a way to palliate it

just by rearranging the elastic properties to form squares-like clusters. I think this case does not correspond to any of your 4 points since I do this without h->inf. In fact, each of those clusters are just 2 FE. Best, David. On Saturday, 11 July 2020 06:19:50 UTC+2, Sebastian Stark wr

Re: [deal.II] dealii installation Mac OS 10.15.5 (Catalina)

Hi Deepak, This is a known issue with the current version of the mac bundle - it doesn't work with Catalina. We are in the process of fixing this. For now, unfortunately, you will have to either use an older version of deal.II or compile it yourself. Sorry, David On Mon, Jun 22, 2020 at 7:

Yes, it seems indeed easy. I'll try to learn how to send it through the official channel in github. On Tuesday, 26 May 2020 05:40:57 UTC+2, Wolfgang Bangerth wrote: > > On 5/25/20 9:20 PM, David F wrote: > > > > I would like to apply many random distortions to a triangu

[deal.II] Using different random seed when distorting a triangulation

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. Best, David. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see
