Generate and Edit Box Refinement Zones

Use the Mesh Controls: Box tool to apply box shaped refinement zones around the entire body of the vehicle, or around individual parts.

Generate Box Refinement Zones Around the Body

  1. From the ultraFluidX ribbon, Setup group, click the Mesh Controls tool.


    Figure 1.
  2. From the secondary tool set, click the body of the Box tool.


    Figure 2.
  3. Select any location on the model body.
    A new refinement zone is generated around the body.


    Figure 3.
  4. Enter a value for Level in the microdialog.
    Note: All mesh controls in the model are defined relative to the far field size, and must be a power of 2 of the far field size. For example, if you define a far field mesh size of 1 m, the available refinement sizes will be 0.5, 0.25, 0.125, etc
Tip: Consecutively clicking generates multiple refinement zones with increasing dimensions.

Generate Box Refinement Zones Around Parts

  1. From the ultraFluidX ribbon, Setup group, click the Mesh Controls tool.


    Figure 4.
  2. From the secondary tool set, click the wheel of the Box tool.


    Figure 5.
  3. Select a part.
    A new refinement zone is generated around the part.


    Figure 6.
  4. Enter a value for Level in the microdialog.
    Note: All mesh controls in the model are defined relative to the far field size, and must be a power of 2 of the far field size. For example, if you define a far field mesh size of 1 m, the available refinement sizes will be 0.5, 0.25, 0.125, etc
Tip: Consecutively clicking generates multiple refinement zones with increasing dimensions.

Resize Box Refinement Zones

  1. Double-click on a box refinement zone in the modeling window.
  2. Edit its dimensions in the following ways:
    • In the microdialog, enter new dimension values.


      Figure 7.
    • Hold left-click and push/pull a selected refinement zone's face to adjust its dimension.


      Figure 8.
Tip: Box refinement zones can also be edited by selecting a zone in the Model Browser and adjusting dimensions in the Property Editor.
