Hello,

one question concerning the new 1D unification features in release 7. Is it now 
possible to use the MeshWorker framework for 1D problems with relatively minor 
modifications? I have tried this for step-12 and I get several exceptions 
stemming from 

dealii::InvalidAccessor (with structdim=0, dim = 1, spacedim = 1)
and 
dealii::InvalidAccessor<0, 1, 1>::InvalidAccessor(dealii::Triangulation<1,1> 
const*, int, int, void const*)

I looked at the documentation and it looks as if, even though 

template<int spacedim>
class TriaAccessor< 0, 1, spacedim >

is now implemented, it still cannot be used to create an iterator for use in 
MeshWorker (as per the class documentation). If this is the case, my best 
attempt at a working step-12 in 1D would be to hand-code the assembly loop?

Is this right, or am I missing something?

thanks!
 -- Mihai
