Set Up Humidity Modeling

  1. From the Flow ribbon, click the Physics tool.

    Figure 1.
  2. Under the Physics models settings, change the flow radio button to Multiphase.
  3. Change the Multifluid type to Humidity transport.
    By default, the Heat Transfer checkbox is turned on.
After setting up the humidity physics, you have the option to define the humidity input when creating inlet boundary conditions.
