Hi all, I am modelling a 3 zone building with active layers to represent radiant floors. I first added the active layer on the ground floor and everything worked fine. Then I tried adding the same active layer to the basement and second floor, but I kept getting "Error in automatic heat transfer calculation for surface 13 or its adjacent surface." as a fatal error. I tried deleting the active layers (all three of them) and replacing them with the original concrete floor, but I still get the error. I have looked at the mailing list archives and did what was suggested, ie. making sure that no internal calculation was used for external sides of any of my wall types. Is it possible that the bug that caused that error was not fixed yet in the 16.01.0002 version of TRNSYS, which I'm using?
