Hi all! I am working on a model with a BHE. I would like to impose the inlet temperature to the BHE as a function of the outlet temperature of the previous hour (or time-step), is this possible? Is is possible to assign the inlet temperature as a formula rather than a fixed value or a time-series?
Thank you in advance for your help,

You can assign the temperature difference as a temperature differential or a power (time-constant or time-varying). It is not possible, however, to input a function. In older FEFLOW versions the user interface only allowed for a fixed/variable inlet temperature. For these, there is a free plug-in that provides the possibility to apply a temperature differential. To apply a specific function, you'd have to develop your own plug-in.

Thank you Peter for your quick reply. Unfortunately I don't have the knowledge to develop my own plug-in, so I guess I'll use excell and find out the values myself for every time-step and create a time series with those values... or at least I will give it a try!
Again, thank you very much indeed!
