the error is:

This looks reasonable. Can you send us the 3D.mphtxt file?
2. the tutorial said triangular and tetrahedral cannot be imported in dealii,
but i can import triangular or tetrahedral element by gridin_COMSOL_mphtxt, is
it controdicory?
deal.II used to use only quadrilaterals and hexahedra until not so long ago,
so the statement about not supporting triangular and tetrahedral meshes was
correct. But it is no longer; can you point out where exactly you found this
statement?
Best
