Daniel,
Thanks for your reply. I had previously used GridIn::read_msh() in 2d in
which case the boundary ids were also correctly read. Isn't it unexpected
behaviour then, if the data is not getting transferred in 3d? Manually
setting the ids will work for now, but eventually I wish the
Vachan,
Maybe the boundary information is not transferred to the deal.II
Triangulation when calling GridIn::read_msh. I would recommend checking the
triangulation after reading it in and modify the boundary indicators
manually if necessary.
Best,
Daniel
