Issues with simulation

[gitfeldhase]

Hello everyone,

I am facing some issues with the simulation and I just can not figure it out where my mistake is.
I tried to run the example simulation_example.py with the attached csv_network as a tree structure (see .zip -> "simulation_tree").
Somehow, the simulation gives me not the correct temperatures (minus degrees even though) the inlet temperature of the producer is set to 90. I just can not figure it out which parameter is set wrong and compared it alot with the csv_network folder of the example but I just do not see a difference.

I would appreciate if somebody could take a quick look on the attached network data, maybe I am missing something very obviously..
tree_example_dhnx.ZIP

Thanks for the great support here!

EDIT
Something that I noticed is, the producers-0 to forks-x pipe is listed very first in the example and in my example it is listed in the last line.
Could this make a difference?
In the results, the temperature of my producer is 90 degree celsius which is correct, all the other temperatures are false (equal or close to ambient temperature.)
End Edit

Best regards
Lars

I feel like the naming is wrong somewhere and the environment temperature is set to all forks.

I checked my files and some had as direction -1.
After switching from and to nodes and changing the direction the simulation worked without bugs and temperatures seem to be fine.

Good to hear! Thanks for checking, @gitfeldhase! I implemented the simulation a while ago but never could test it on larger networks. If you like, feel free to add another example based on your calculations!

Sadly, I have not been working on this topic for a while and will not pick it up in the near future. Therefore, I will not be able to spend large amounts of time on DHNx. I learned that knowing about how much original developers are still involved can help, so I wanted to let you know about this. Feel free to take responsibility when finding bugs or you have ideas for improvements!
