Hi Everyone,

I've been trying to regenerate the 2U exchanger example of the FEFLOW book by Diersch (page 705, section 13.6.4) as a practice. It's a comparison between numerical and analytical BHE solutions simulating a single 2U BHE. I'm setting everything up according to the book. Eskilson's method runs fine and the results agree with those presented by Diersch, but in terms of the numerical method temperature starts to rise to some unrealistically high values. I don't change any settings when I switch between the two methods. Is there something that I'm missing? 
I even tried upwinding scheme, but it resulted more or less the same.

Thanks,
Negar

Hi,

Does anyone know how can I assign BHE or multilayer wells using edges and not join edges? It seems impossible to select the right edges in a finely meshed model? And "Select by Expression" doesn't work either while trying to select an edge.

Thanks,
Negar
