Re: [TRNSYS-users] Type 56 , active Layers



John,
I have run into this error myself but have never been able to track down the reason for it. I have always solved it reducing the minimum flow that I am requesting Type56 to accept (which may cause it to autosegment).
Kind regards,
David

Are active layers required to have fluid flowing always at minimum, or only
when non-zero?

I am receiving an error :
Specific fluid mass flow of active layer in surface 26 below minimum value
of 2.87 kg/m^2.h Please increase the minimum mass flow rate or use the
autosegmentation feature of TRNBuild for subdividing the surface.

I have checked the active layer, it won't auto-segment > 1 And the listed min allowed inlet mass flowrate is listed as 3.57 kg/m^2.h
not the 2.87 kg/m^2.h given in the error message.

I multiplied the area of each floor times the min flow rate for the zone
And set it as an alternative flow, but I still get the ame error.

Thanks for any ideas.
