Hey,
my guess would be, that the 1d hyper_cube is "colored" and has the
boundary indicator of 0 at the left end and of 1 at the right end.
Could you please try adding
VectorTools::interpolate_boundary_values (dof_handler,
1,
BoundaryValues<dim>(),
boundary_values);
after the other interpolate_boundary_values(..) call?
@others: The documentation isn't great here but hyper_cube uses
hyper_rect with colorize=false. 1D is somewhat special in this case.
