Creating the Fluid Region

To use the Onera M6 wing in a simulation, you first convert the model to a geometry part, and then assign the part to a region. After creating the region, the outer boundary is set to a free-stream boundary which allows you to model free-stream conditions in the far-field.

To create the geometry part and assign it:
  1. Right-click the Geometry > 3D-CAD Models > Onera M6 Wing node and select New Geometry Part.
  2. In the Parts Creation Options dialog, click OK to close the dialog. The default settings are acceptable.
  3. To create a region for the fluid volume:
    1. Right-click the Geometry > Parts > Fluid node and select Assign Parts to Regions....
    2. In the Assign Parts to Regions dialog, select:
      1. Create a Boundary for Each Part Surface
      2. Do Not Create Interfaces From Contacts
    3. In the box to the right of Create One Region for All Parts, enter the target region name, Fluid.
    4. Click Apply then Close.
    One region is created with boundaries that define the wing and domain.
  4. To view the regions, create a geometry scene.
Before generating the volume mesh, one of the best practices is to set the boundary types for the flow boundaries.
  1. Select Regions > Fluid > Boundaries > Fluid.Farfield node and set Type to Free Stream.
  2. Select the Fluid.Symmetry node and set Type to Symmetry Plane.
  3. Save the simulation.
