Hi All,
I'm having problem when applying periodicity on meshes generated with Gmsh
or Abaqus. The problem arises when I run in parallel (in serial it works)
getting the following error:
void
dealii::GridTools::match_periodic_face_pairs(std::set<std::pair<CellIterator,
unsigned int> >&, std::set<std::pair<typename
dealii::identity<RangeType>::type, unsigned int> >&, int,
std::vector<dealii::GridTools::PeriodicFacePair<CellIterator> >&, const
dealii::Tensor<1, typename FaceIterator::AccessorType:: space_dimension>&,
const dealii::FullMatrix<double>&) [with CellIterator =
dealii::TriaIterator<dealii::CellAccessor<3, 3> >; typename
dealii::identity<RangeType>::type =
dealii::TriaIterator<dealii::CellAccessor<3, 3> >; typename
FaceIterator::AccessorType = dealii::CellAccessor<3, 3>]
The violated condition was:
n_matches == pairs1.size() && pairs2.size() == 0
The name and call sequence of the exception was:
ExcMessage ("Unmatched faces on periodic boundaries")
Additional Information:
Unmatched faces on periodic boundaries
I suspect that match_periodic_face_pairs function does not have access to
the whole faces in parallel.
I am wondering if you have encountered this issue before, or any clue what
is the reason for this issue.
Thanks in advance.
Hamed
