Hi Oded,
I wasn't able to read in the .cub file (clearly its not backwards
compatible). I did manage to import the .inp file and nothing looks amiss.
Could you try to set the apply_all_indicators_to_manifolds
<https://www.dealii.org/developer/doxygen/deal.II/classGridIn.html#a51f7977b217e305d3538574cbd3d3a01>
flag
to true? Its possible that one of the boundary id's is being set to an
internal face. I've had this bug crop up on occasion for unstructured
meshes, but never for structured ones. If this fixes the problem then
you'll have to recreate all of the boundary ID's yourself for the time
being until the bug is fixed.
Regards,
J-P
