Yeah, a complete remesh is an entirely different story, but if you have a look in the documentation of FE_Field_Function, these two lines <https://github.com/dealii/dealii/blob/master/include/deal.II/numerics/fe_field_function.h#L101-L102> in particular, you will be happy to find that this *might* not be too difficult to implement either. > get cubit to export codimension 1 surfaces using its export commands.

Yes, GridIn::read_abaqus will definitely not cater for that case as it doesn't distinguish between dim and spacedim, but it might be an easy fix <https://github.com/dealii/dealii/blob/c839b43a783bfa717b38ba0bc7d345ec7096dcae/source/grid/grid_in.cc#L2996-L3012> . > I will try VectorTools::interpolate_to_different_mesh > <https://www.dealii.org/developer/doxygen/deal.II/namespaceVectorTools.html#af68148d58c8dfd0916eceab9d89d74d5> > > when I get to my desk this morning.

This class makes heavy use of the GridTools::find_cell_around_point function, and *perhaps* (pure speculation) it may not be sufficiently robust codim 1. Perhaps someone more knowledgable on the inner functioning / use of this class would like to comment on this point?
