Hi
I am trying to extract all degrees of freedom which are at the boundary and
belong to specified components using DoFTools::extract_boundary_dofs()
function and IndexSet for a parallel distributed triangulation. Now, how I
can iterate over the IndexSet and how I can access to the Dof index in it?
Something like this:
dealii::IndexSet::ElementIterator index = in_set.begin(), endind
= in_set.end();
for (; index!=endind; ++index)
{
how to access to dof index here?
}
Thank you
