Generate Body-Fitted Refinement Zones

Use the Mesh Controls: Offset tool to refine mesh within a given distance from the entire vehicle body.

As opposed to the Mesh Controls: Box tool, which creates a box-shaped refinement zone, the mesh refinement patterns of the Mesh Controls: Offset tool follow the contour of the body itself. This creates refinement around the body where it is needed most, eliminating unnecessary refinement that may result from a box-shaped zone.
  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 Offset tool.

    Figure 2.
  3. Select a point on the model body.
  4. Choose whether to define the refinement zone based on distance or layers using the drop-down menu in the microdialog.
  5. Specify the distance or number of layers for the refinement zone.
    • Enter a value in the microdialog.
    • Drag the slider up and down.

    Figure 3.
  6. Enter a value for Level.
    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
  • Consecutively clicking generates multiple refinement zones with increasing dimensions.
  • Modify the refinement zone's dimensions in the Property Editor.
