Defining a Mass Flow Split Outlet

You can define the proportion of the mass flow leaving the fluid region for each outlet in your simulation.

Before you begin:

Your simulation must satisfy the following conditions to support mass flow split outlets:

  • You can create a mass flow split outlet only when mass flow inlets are defined for all the inlets.
  • All outlets must be mass flow split outlets. You cannot define a pressure outlet for any of the outlets in the simulation.

  1. From the Conditions section of the Flow analysis assistant panel, click Mass Flow Split Outlet .
  2. Optional: Enter a descriptive name.
  3. Select the surface where fluid leaves the domain.
  4. Assign a weight to the mass flow leaving through the selected outlet. For example, if you create two mass flow split outlets with weights specified as 2 and 1, twice as much mass flows out of the first outlet as the second.
