[dune-pdelab] Using physical groups in gmsh for boundary conditions

[Alexander Schlaich]

Dear all,

I'd like to use physical groups for setting boundary conditions in a
read-in gmsh mesh using UG, according to the commented section in the
example listing 17 of pdelab howto.

But using i.boundarySegmentIndex() I get:

boundaries.hh:96: error: 'const class
Dune::PDELab::IntersectionGeometry<Dune::Intersection<const
Dune::UGGrid<2>, Dune::UGGridLeafIntersection> >' has no member named
'boundarySegmentIndex'

I'm using recent trunk of pdelab and other dune modules.


How can I access the physical groups?


Thanks for your answers,
