My main intention at this moment is not balancing but as U mention "blow air throught existing geometry and spit out the numbers". All is need to know after finishing a ductwork model is a pressure loss at the worst path to be able to get a proper fan or ahu. A duct sizing utility tool is showing only a linear losses, not a local losses (on a elbows, transitions etc) so I U also see a calculations are not accurate.
To sum up this this discusion does anyone know is there a program for aecosim like magicad for revit to calculate a whole pressure losses on a ductwork?
