Define Baffle Surfaces

Use the Baffles tool to define baffle surfaces.

Baffles can be defined on a topological baffle surface, or any surface based on simulation needs. During the solver run, baffles will be split into two faces and results will be available on both sides.

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

    Figure 1.
  2. Using the guide bar selector, choose whether to define the boundary condition on Surfaces or Thin Solids.
    Note: You can only select thin solids if layers have been defined using the Thin tool.
  3. Select surfaces/thin solids.
    If the Filter non baffle surfaces option is active, only topological baffles are available for selection; the rest of the surfaces are transparent. Turn off this option to select non-topological surfaces.
  4. For thin solids, select a direction option from the guide bar.
    Option Description
    Direction: Away from Parent Surface Define the condition on the boundary surface furthest from the parent surface.
    Direction: Adjacent to Parent Surface Define the condition on the boundary surface closest to the parent surface.
    Direction: Both Sides Define the condition on both sides of the boundary surface.
  5. In the dialog, input values for each tab.
    • Turbulence
    • Temperature
      Note: This tab only becomes available if the Heat Transfer option is turned on in the Flow ribbon Physics tool.
    • Setting
  6. 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.
