[deal.II] Re: dealii on Apple M1
Hi, Yes, i got success. I used gcc,cmake, and other app/libs from homebrew. Everything works fine. I had some problems with homebrew at december, but now it works fine. понедельник, 13 сентября 2021 г. в 15:10:36 UTC+3, deepak@gmail.com: > Hi Alex, > > I have the same struggle.

[deal.II] dealii on Apple M1
Hi All, Has anyone tried to compile dealii for Apple M1 ? Can you share your experience? I've tried to do this for version 9.2 without success. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.

Thanks, the answer is in the papers (Guermond, 1995, eq 5.11, Guermond,
1998, eq 3.5). Actually we find and use non-solenoidal (intermediate) u^k
on the diffusion step.
"The _projected_ velocity can be completely _eliminated_ from the algorithm
and the _intermediate_ velocity is the only one of interest." (Guermond,
1998)
As I understand, we don't need the projected (solenoidal) velocity for the
calculation.

[deal.II] Please explain the projection method (tutorial step-35)
Hello,
In step-35 we find u^{k+1} (diffusion step)
Then we find \phi^{k+1} (projection step) and correct p^{k+1} pressure.
But why we don't correct u^{k+1} velocity? I think u^{k+1} must be
solenoidal but it is not.
