<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Benedikt.<br>
<br>
I am a bit surprised since from earlier (a lot earlier) emails<br>
I got the impression that this removal was due to a discussion between Peter, yourself and (I think) Oliver.<br>
I can not find that emails any more where this discussion was started.<br>
All of this is a few years old and the boundarySegmentIndex was the result of this.<br>
<br>
At the moment it is not possible to easily replace the original boundaryId with the boundarySegmentIndex
<br>
and if you have to do quite a bit of work yourself. <br>
To get the information out of the dgf parser there is a method<br>
template< class GridImp, template< class > class IntersectionImp ><br>
const DGFBoundaryParameter::type & <br>
GridPtr::parameters ( const Intersection< GridImp, IntersectionImp > & intersection ) const<br>
which returns the boundaryId for a given intersection (assuming that it lies on the boundary). Then you could store these ids in a vector<br>
using intersection.boundarySegmentIndex(). <br>
<br>
Parallel is (as Oli mentioned) still a problem. <br>
If gmsh is better suited then DGF I can not say. No idea how <br>
boundary identifiers are transported through the gmsh reader<br>
but the problem with parallel are the same.<br>
<br>
I should add that I have never testes this since I also still use<br>
the boundaryId....<br>
<br>
Best<br>
Andreas<br>

<div>Dear Dune,</div>
<div><br>
</div>
<div><br>
</div>
<div>I was woken up somewhat by the recent discussion on 'boundaryId'</div>
<div>and the fact that it is marked at 'deprecated'. Now, since we need the boundarId</div>
<div>quite much, what would be the 'clean Dune style' of using id's on boundary faces ?</div>
<div><br>
</div>
<div>Should we use</div>

<div><br>
</div>
<div>Also, how would we use this in the parallel case ? This is most relevant for us.</div>
<div><br>

<div>Would it be wiser to not used DGF but read directly from gmsh ?</div>
