[TRNSYS-users] Active layer dividing

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.

Aaron,
  Type93 will do exactly that.
Best,

In the simulation studio I am using the equation feature.  For the first time step, I need a variable in the equation to be some defined constant value, for the following time step I need that variable to be the output of another component of the previous time step.  Does anyone know how to do this?
