Hi everyone,

I saw two different ways to compute integral on internal edges and I was wondering which one is the right one. I saw using

intalledges(Th)((1-nTonEdge)*p)

and

intalledges(Th)(p/nTonEdge);

I think this depends on your numerical algorithm.The general jump is defined as taking 0 on the boundary edge of the area. So I think the right way should be
intalledges(Th)((1-nTonEdge)*p/nTonEdge).

Maybe you can look at this example to see what I mean.

I want to compute the normal component of the mean of a vector on internal edges
