Hi everbody! I have a question concerning the active layer. While I was trying to implement active layers in a building structure, compiling the .bui file I got the following message: "The min. desired inlet mass flowrate is smaller than the min. allowed inlet mass flowrate. You may use autosegmentation MinflowCalc=11.0326 MFLOWMIN=10" I thought MFLOWMIN was calculated from the piping features (diameter, length), in order to avoid transition to laminar flow, as it sounded reasonable, is it correct? So I tried to change the MinflowCalc from 10 to 11 in the specification window of the surface in the building model (TRNBUILD). Then, when I compile it the second time I get the same message: "The min. desired inlet mass flowrate is smaller than the min. allowed omòet mass flowrate. You may use autosegmentation MinflowCalc=11.05... MFLOWMIN=11" What do MFLOWMIN and MinflowCalc mean? Does MinflowCalc depend only on geometrical features? Can anyone help me in setting these features correcly? Thank you in advance Filippo. --
