Cell Orientations not communicated in parallel

[Stephan Schmidt]

The internal cell orientation vector does not seem to be properly communicated in parallel for a shell mesh. Please see attached minimal example. In serial, inner(n(+), n(-)) == 1 on the straight sides of a cube, in parallel this is not the case.

[Stephan Schmidt]

This is the expected output in serial: Inner(n(+), n(-)) is zero on the straight sided facets

‌

in parallel, each processor does not seem to know the orientation of the normal on the opposite side
