Discrete Feature Element heat transport

Remembering another question concerning Discrete Feature Elements just poped back to my mind.

I start up with a 2D Modell. I want to simulate a heat flow transport along a tube. Using the manning Strickler equation. I put the discrete element somewhere to the middle of my model. When calculating now the heatflow the temperature changes at the point of inflow and the point of outflow but it is not calculated along the tube. It seems as if the tube is isolated or even ignored in the calculation. Is it possible to calculate alongside? How?

Thanks a lot for your help

In a finite element model, results are only calculated at the nodes. As there are no calculation nodes along one section of a discrete element, you will not get any results in between.
