Air density / Pressure drop

We are trying a ducting work for air distribution. We placed 1.4kg/s at duct inlet and atmospheric pressure at duct outlet and we have seen big differences between the results obtained here and Autodesk CFD. Double difference

Hey there!

Please provide a more detailed description so we can give support:

  • Include the URL to your project
  • Show us your reference simulation, including setup
  • Explain what is your variable of control and how you are measuring it
  • Did you already perform a mesh independence study? (On both platforms!)
