Hello, I have a question about 2D axisysmmetric models for the injection and extraction of hot water into an aquifer.  The left radial axis should represent my well screen section. I already tried Well BC 4th kind for every node of the well screen and divide the desired flow rate by the total number of nodes. But I want to simulate it more realistic like a MLW in 3D. My idea was putting a Discrete Feature Element along the well screen edges and put a well BC at the top of the DFE, to simulate hot water entering the well and the aquifer from the top. However, if i put the DFE at the left most edges, the water of the Well BC does not flow along the DFE into the aquifer. I tried putting the edges and nodes of the line for the DFE 0.1m away from the left boundary (having a radius for the well of 0.1m) and then it works fine. I can imagine that this is because of the axial symmetry and that the radius and area of the DFE then would be 0, if its on the left boundary. So I'm wondering if this would be the correct way to do it in FEFLOW? Thanks, Max
