All,
the link to it is somewhere further down in the announcement, but I'd like to
highlight as always the paper in which we summarize the major improvements in
this version:
  https://www.dealii.org/deal92-preprint.pdf
You may find it interesting.

As always, many many people have contributed to this release. In
addition to the 17 authors of the paper above, section 4 lists another 79
people, also listed below. I think that's an awesome number, and we owe all of 
them for all of their contributions -- thank you!

[deal.II] Xcode as an IDE for deal.II

2020-06-11 Thread Siva Nadarajah

Dear All, 
My group has been using deal.ii for the past two years. I just switched to 
using XCode. I have a problem where std::cout does write out to the console 
within Xcode, but I do see it when the code runs on command line. Any 
thoughts?
Best Regards,
Siva

Dear Peter,
 Thanks for the reply. It gives the following error

It seems that the link you send me explains that I have to create serial
triangulation and then apply periodicity?

[deal.II] Is it possible to copy_triangulation for fullydistributed with periodic face?

2020-06-11 Thread heena patel

Dear all,
 I am trying to solve semilagrangian advection 
problem?
I have traingulation with periodic face.
I wanted to copy_triangulation and trace back mesh. The thing is with *parallel 
distributed triangulation* it refuse to copy for refine mesh, that is 
written in documentation as well. When  I try to use fullydistributed 
triangulation it gives me error with periodicity. Is there a way that I can 
copy triangulation with periodicity or I am missing something? The code 
works if I create new_triangulation with parallel distributed triangulation 
and work on it. But it is expensive step. Kindly find code in attachment.


Regards,
Heena
