Thanks a lot for your reply and helpful suggestions. About my second question, due to the fact that in Feflow there are no dry cells even if I do not insert a recharge on top as result I see isolines going from the top to the bottom of the model even if my water table is 15-20 m below the ground and I can visualize the hydraulic head in the first layers which are actually not characterised by the presence of groundwaters.I wonder if there is a way to visualize the hydraulic head only in layer that are actually characterised by the presence of groundwater.
Thanks in advance

Dear everyone,
I have two problems, maybe trivial: the first is how can I visualize the real velocity instead of Darcy velocity (elemental and nodal). The second is about hydraulic level. I have simulated a phreatic aquifer using phreatic status in the first slice and dependent for the others slices. My layers are 5 m thick and the water table is from 15 to 20 m below the ground level. My model has also a recharge on the top (inflow on top).Is that way correct? Because as result I obtain a phreatic level which is correct in value but which is represented also in the first three slides...and varies from first to second or third slice...in addition if I view the hydraulic head in a cross-section I see  isolines going from the top to the bottom of the model, but the top should consist of "dry cells", so the isolines should start after the "dry cells" (i.e. forth or fifth layer).Is that correct?Is there any way to visualise it in a different way?

Best Regards

Thanks a lot for your suggestions.

Thanks for your reply! I know that vertical refining is useful for that kind of problem. But as I have found this kind of problem especially in area with more horizontal refining, I was wondering if even the difference between horizontal refining (from 0,05 to 0,1) and vertical refining (1 m) could be an important factor. Thanks.

Hi, I am modelling an open loop system (hot injection) with Feflow 6.2 using multilayer well. My problem is that below the well and thermal affected hot zone I find a kind of inverse thermal affected cold zone. I have already verified Delaunay criterion and Peclet number. Could the problem be due to the difference between horizontal discretization (0,1-0,05 m ) and vertical discretization (1m)?Thanks for your suggestions!

Hello! I have just started working with Feflow and I have two questions:

I need to know how to model a dispersion tank and a drain.

Could anyone help me?

Thanks!!!!
