Re: [TRNSYS-users] Error

Meryem,
  your FENÊTRE_120 is set to use the "internal calculation" algorithm for the convective heat transfer coefficient on both the front and back side. However, FENÊTRE_120 is used as an external window and cannot be if its back side convective heat transfer coefficient is calculated internally. The algorithm used is for natural convection heat transfer but the outside of buildings are much more dominated by forced convection so Type56 does not allow you to use the "internal calculation" algorithm for external surfaces.
Regards,

Hello,

 

 In my project TRNSYS version 17, when I run the calculation, I get an error that I cannot fix:

******Fatal Error at time: 0.000000 Generated by Unit: 56Generated by Type: 56 Message: Error in automatic calculation for heat transfer surface 0 or its adjacent surface!: Automatic heat transfer calculation Is Only  Allowed on surfaces Within a zone. Please check building input file (.  bui)!*

 

enclosed my project
