Thank you for your input! That was my first attempt at tackling this. However,
I run into problems with the line
for(const auto & face : cell-> face_iterators()).
No matter what member function I choose off of the DoFCellAccessor class
template reference, I get some version of the following:
class dealii::DoFCellAccessor<dealii::DoFHandler<1, 1>, false>’ has no member
named ‘face_iterators’; did you mean ‘face_iterator’?
I'm pretty sure that function should exist. What deal.II version are you using?
But, if that doesn't work, you can always do this instead
```
for(const auto & cell : triangulation.active_cell_iterators())
for (unsigned int f=0; f<GeometryInfo<dim>::faces_per_cell; ++f)
{
const auto face = cell->face(f);
if(face->at_boundary() && face->boundary_id() == 1)
// do something useful
}
```
Best
W.
