Hi,
I'm working with Trnsys 17 and I haven't had this kind of error until now:
"Specific fluid mass flow of active layer in surface 22 below minimum value of 3.89 kg/m2h Please, increase the minimum mass flow rate or use the autosegmentation feature of TRNBuild for subdividing the surface."
I have tried everything, from increasing the desired flow rate, autosegmentating the surface to changing the type of wall without active layer or deleting the surface, but the error persists and I don't know what more to do.
