Define Inlets with Constant Velocity

Use the Constant tool to define an opening surface with a constant velocity.

User-defined velocity, in any co-ordinate system, is imposed on all the nodes of a selected surface.

  1. Select the surfaces on which to apply the boundary condition in the following ways:
    • While in the Flow ribbon, select surfaces, then right-click and select Assign Inlet > Constant from the context menu.
    • From the Flow ribbon, click the Constant tool.

      Figure 1.

      Select surfaces.

  2. In the dialog, input values for each tab.
    • Momentum
    • Turbulence
    • Temperature
      Note: This tab only becomes available if the Heat Transfer option is turned on in the Flow ribbon Physics tool.
    • Setting
  3. From the guide bar, execute the command in the following ways:
    • Click to confirm your selection and remain in the tool.

      This allows you to continue creating instances and helps you visualize and edit instances with the legend.

    • Click to confirm your selection and exit the tool.
