To define an inflow condition on a boundary section, do the following:
Select the Inflow menu item in the list of boundary condition choices.
Inflow
Enter the value of flow rate, when prompted.
Note: The flow rate can be mass flow rate or volumetric flow rate.
For generalized Newtonian flow, select the method to compute the inflow: Automatic (which lets Ansys Polyflow choose the appropriate method for you), Fully developed, or Constant normal force. These methods are described in Inflow Calculation for Generalized Newtonian Flow. Keep the default selection of Automatic, to allow Ansys Polyflow to choose the method for you.
Automatic
Select the type of flow rate: volumetric flow rate or mass flow rate.
The default type is Volumetric flow rate.
Volumetric flow rate
Note: If you select Mass flow rate, you must define a positive and constant density.
For multiple-material coextrusion flows, select the material assigned to this inflow condition.
Modify incoming material
