Greetings fellow members,

As its name suggests, intalledges integrates on all edges (interior and boundary alike). Then how to integrate on internal edges only ?

Best regards.

You have a quantity named `nTonEdge`

assciated to each edge, that contains the number of triangles touching the edge. Its value is thus 2 for internal edge, and 1 for boundary edge.

You can just then mutiply your expression in `intalledges`

by `(nTonEdge-1)`

, this will give zero for the boundary terms, and 1 for internal terms. For example

`+intalledges(Th)(mean(u)*jump(v)*(nTonEdge-1))`

Excellent, thank you !
