I model a building with underfloor heating and when I run my simulation I got the following message.
'Specific fluid mass flow of active layer in surface 26 below minimum value of14.49 kg/m2h Please, increase the minimum mass flow rate or use the autosegmentation feature of TRNBuild for subdividing the surface.'
I know that this is a common problem but I have already use the autosegmentation feature and also the flow which I assign in this specific active layer is more that the double than the minimum allowed inlet mass flowrate. So I cannot understand why I got this message. If anyone has any idea it will be very helpful for me.
Thank you.
