Active Layer

[Moritz Köpcke <moritz.koepcke@xxxxxxxxxxxxxxxxxx>]

Dear TRNSYS users,

 

please give me somebody a hint, what could be meant by: "UNABLE TO FIND A ROOT AFTER INDICATION THAT A ROOT EXISTED". That is an error message generated by PREBID during the transfer function coefficients calculation, because of my active layer. I believe I designed it properly (cold ceiling modules), but after quite a while, I still cannot find the problem:

 

WALL KMODUL2
 LAYERS   = ALUMINIUM KLAYER ALUMINIUM LDECKE BET150 STWOLL012 ESTRICH45 PVCBEL
 THICKNESS= 0.036     0      0.005     0      0.15   0.05      0.045     0.002 
 ABS-FRONT= 0.6   : ABS-BACK= 0.6 
 HFRONT   = 11 : HBACK= 11

 

whereas

LAYER KLAYER
 PSPACING=   0.12 : PDIAMETER=   0.01 : PWALLTHICKNESS=  0.001 : PCONDUCTIVITY= 1382.4 : CPFLUID= 4.18

and

LAYER LDECKE
 RESISTANCE=     1.25

 

I also tried different time bases. And another short question: How is it defined, that the modules hang below the ceiling and do not lay on the floor or are even vertical boundaries?

Thank you very much!

Moritz
