The error is not coming from dealii.
I made it work. With:
1) I first had to reordered the elements (not so difficult, i'm using
PointWise for that). Then i've got only 2*direction and 2*direction+1 as
face numbers on the same boundary Id.
2) I changed the tolerance (hard coded) in the orthogonal_equality
(point overloading function version). It's 1e-10 at default, i put 1e-7,
and it's working well.
Is there a way to elegantly change the hard coded tolerance ? Or is it
possible to add a non mandatory tolerance parameter to the function
collect_periodic_faces, with default value 1e-10 ?
Thanks,
Best,
Yann

I do not know the function in question in detail, but have you tried
reading through the implementation of that function and understanding
where the error comes from? Oftentimes, understanding how an error comes
about gets you 90% the way towards understanding how to fix the code (in
your own application, or perhaps in deal.II itself).

Hello,
I'm trying to define periodic constrains on a "complex" geometry. It's
working fine in parallel when the periodic faces are collinear to the
directions (in my case X and Y directions). But in the "Z" direction,
i've got inclined faces.
I tried to use the function collect_periodic_faces which do not use
orthogonal_equality(), as i've got inclined faces.To do so, i've put
both boundaries inside one boundary Id. But the error i've got is :
The violated condition was:
pairs1.size() > 0
Additional information:
No new periodic face pairs have been found. Are you sure that you've
selected the correct boundary id's and that the coarsest level
mesh is
colorized?
I've checked the orientation of all the faces of the mesh. They are all
True.
Maybe i did not understood the way to use the function
collect_periodic_faces using the standard orientation.
Do you have some insights on how to define correctly this periodicity ?
Thanks,
Yann
