Box Refinement Zones

  1. From the Setup ribbon, click the Mesh Controls tool.
  2. From the secondary tool set, click the Body Box Zone tool.
    Figure 1.
  3. Select any location on the model body.
    A new refinement zone is generated around the body and the Box Zone micro-dialog appears.
  4. From the Box Zone micro-dialog, enter a value of 5 for Level, 6.951 m for Length, 2.776 m for Width, 1.783 m for Height, and press Enter.
  5. In the Property Editor, set Zone Extents > X Min to -1.407 m and rename your box by setting General > Name to RL05_Box.
  6. From the Box Zone micro-dialog, click Plus.
    A second box refinement zone, one level coarser is generated.
  7. Repeat Steps 4-6 for zones 4, 3, 2, and 1 using the values provided in the table below.
    Table 1.
    Level Name Length Width Height X Min
    4 RL04_Box 8.937 m 3.416 m 2.139 m -1.904 m
    3 RL03_Box 11.420 m 4.270 m 2.496 m -2.400 m
    2 RL02_Box 14.895 m 5.338 m 2.852 m -3.390 m
    1 RL01_Box 24.825 m 6.405 m 3.565 m -5.880 m
    Note: The Length, Width, Height, and X Min values the table above are calculated from equations provided in the ultraFluidX 2023.0 Setup guidelines for vehicle aerodynamics.
    Note: Alternatively, you may use the Part Box Zone tool to prescribe a refinement zone around a single part.
