Run Wrapping

Use the Wrap: Run tool to create wrap from selected parts.

The Wrap tools work for tessellated geometry. If the input is b-spline geometry, first convert to discrete geometry using the Convert tool.

If local and proximity controls are defined, they will override the default settings defined in this tool.

  1. From the Geometry ribbon, click the Wrap > Run tool.

  2. Select parts to wrap.
  3. In the dialog, select a wrapping method.
    • Tight Wrap
    • CAD Wrap
    Tight wrap uses a traditional wrapping mechanism whereas CAD wrap keeps the original geometry shape as it is and just fixes areas of issue.
  4. For tight wrap:
    1. Choose whether to wrap the exterior of your selection or the cavity.
    2. Choose a volume definition.
      • All - wrap all volumes
      • Consider enclosed seeds - wrap volume enclosed by defined seed nodes
      • Volume Index - useful to get largest or second largest volume
      • Exclude enclosed seeds - wrap all volumes but not volumes with enclosed seed nodes

      If needed, use the guide bar selector to define enclosed seeds.

    3. Define remaining wrap parameters.
    4. Click Run.
      After tight wrapping, the generated result is placed in the first selected part and the part is renamed as “CFD wrap 1”. Since the wrapped form is manifold, results can be one or multiple solids. The input selection is removed in order to avoid duplication.
  5. For CAD wrap:
    1. Choose whether to wrap the exterior of your selection or the cavity.
    2. Define remaining wrap parameters.
    3. Select enclosed seed nodes.
    4. Click Run.
