Hello @MingboPeng -
I am testing the default Ironbug Systm_04_SZHP_All_Elec and it is not working. it says: 1. Solution exception:Airloop needs at least one fan!
Do you know what might be the issue? I just updated my whole script to 1.6.0, and I am not sure if there is something there not working.
Attached the simplified model.
