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 25: 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.
