Hello,

I am simulating a BHE array in FeFlow. I have noticed a weird time discrepancy occuring: E.g. at the time t=0.5d I change the inlet temperature from 10 to 28°C (see attached screenshot, right hand side). However after simulating the specified time period, FeFlow shows the inlet temperature change only 1 hour later (screenshot, left hand side). Why is that? Is this an error? How can I change this behaviour? I see the same time discrepancy when using python, however the discrepancy is 1 hour larger.

Also: When using python with the ifm module, which callback function should I use to retrieve BHE output temperature values (among others) for each simulated time step? preTimeStep, postTimeStep or a different function?

Thanks in advance
Benedikt
