Run Adaptive Wrapping

Use the Wrap: Adaptive tool to create traditional tight or loose wrap from selected parts.

1. From the Discrete ribbon, click the Wrap > Adaptive tool.

   
   
   Figure 1.

2. Select parts to wrap.
3. In the dialog, select a wrapping method.
   • Tight Wrap - Creates a wrapped surface mesh which adheres as closely as possible to the original topology representation, automatically detecting and following the surface features of the model.

     The accuracy of the output is dictated by the element size. The larger the element size the less detail, the smaller the element size the more detail. This algorithm works differently than the loose wrap in that it projects the nodes of the wrap to the original mesh, hence it is able to more accurately capture features.

   • Loose Wrap - Wraps the selected parts with the target element size specified, and outputs an outer-volume mesh which approximately adheres to the original topology.

     A smaller element size generates a wrap mesh that more closely approximates the original representation and adheres to more features; a larger element size produces a more basic mesh which ignores more features. The loose wrap does not project the nodes of the wrap mesh to the original mesh, and typically the wrap mesh will have an offset from the original mesh. Again, the offset is dependent on the target element size used.

4. 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.
5. Define remaining wrap parameters.
6. 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.
