Dear deal.ii community,
I am working with a mesh that is imported via a modified version of
GridIn::read_abaqus(). I'm able to run my mesh and job with
parallel::shared without any issues.
However, when I go to use parallel::distributed, I run into an issue with
p8est connectivity:
void dealii::parallel::distributed::Triangulation<dim,
spacedim>::copy_new_triangulation_to_p4est(std::integral_constant<int, 3>)
[with int dim = 3; int spacedim = 3]
The violated condition was:
p8est_connectivity_is_valid(connectivity) == 1
It seems that this is a known issue:
https://github.com/dealii/dealii/issues/7428
I've read through the issue thread, but I don't fully understand what is
going on. It's not clear to me if this is a bug with p4est or with
deal.ii. There is a listed work-around that seems to rearrange the nodes,
but I'm not sure if that's applicable in my situation.
Can you help me out by answering a couple questions?
- Is there a work-around for this issue?
- Is there an alternative to p4est?
- Are there modifications I can make to my mesh/program to avoid this
issue?
- What would be involved with fixing the bug?
On a possibly related issue:
- What is needed to allow for simplex meshes with
parallel::distributed? Is this also a connectivity issue?
Many thanks,
Alex
