<br>
thanks for your answer.<br>
<div>Sorry but I'm a bit perplexed about the method "numberInSelf()" ... I tried to call it, but I get an error from the compiler, saying that there is no such method.<br>
To which class does it belong? I didn't find it in the documentation.<br>
<br>
The subIndex method is from IntersectionIterator? Or from elsewhere?<br>
<div style="font-family:Tahoma; font-size:13px"><br>
Cheers,<br>
Andrea<br>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi.<br>
Definitely a dune question:<br>
<br>
Probably the easiest way is to use the codim 1 subentity which (in the case of alberta) corresponds to the intersection, i.e., e=intersection.numberInSelf().<br>
Then you can get the index of your corners for that edge by using the subIndex method.<br>
Best<br>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi everyone,<br>
<br>
I have a quick question about the Intersection Iterator. Before starting, I'm using AlbertGrid.<br>
<br>
Suppose you have a triangle ABC, and you need to perform some operations related to its boundary edges, i.e., the three segments AB, AC, BC.<br>
When you call the intersection iterator, you get three iterators, one for each edge. So far, so good.<br>
But what is the correspondence? I mean, iterator -> geometry().corner(0) gives you the local first corner of the codim-1 entity. To which global vertex does it correspond? A, B or C?<br>
<br>
I'm not even sure if this question is related to DUNE in general, or maybe should be addressed to DUNE-FEM.<br>
<div>Thanks for your help!<br>
<br>
Andrea<br>
