[TRNSYS-users] Active layer dividing

[王洋]

Dear all,

I defined a active layer, but it shows ERROR as follows:




 Fatal Error at time   :         0.350000
    Generated by Unit     :     4
    Generated by Type     :    56
    Message               : Specific fluid mass flow of active layer in
surface   7 below minimum value of 5.35 kg/m2h Please, increase the minimum
mass flow rate or use the autosegmentation feature of TRNBuild for
subdividing the surface.



But the min. allowed inlet mass flowrate is 5.37 kg/m2h, I defined the min.
desired inlet mass flowrate is 5.4 kg/m2h.
The ATTACHED is the detailed setting of ACTIVE LAYER SPECIFICATION. Please
have a look and tell me how to correctly define them?

Please tell me how to increase the minimum mass flow rate? Where is it in
detail? I want to get only one surface not dividing it. Please tell me how
to get only one segmentation in detail?


Many thanks!


Br.
