In CFD modeling, input parts can have topology issues, like free surfaces and self-intersections, and part assembly
issues, such as parts with very close proximity and intersecting parts. Manually connecting these parts can be time
consuming and require expertise in certain tools. The Wrap tool can generate a watertight manifold model from dirty input with considerably less manual work.
When performing cleanup or defining simulation parameters, it can be helpful to first find and isolate certain types
of geometry. This will give you a better idea of the areas in the model you need to focus on.

Use the Wrap: Leak Check tool to detect leaks in your model
before wrapping.
When you have to wrap parts, it is important to first check for leaks to avoid any
unnecessary regions being captured in the wrapping process. Leaks are found by
tracing available paths between enclosed seed nodes and target nodes through gaps
bigger than a given leak search size.
From the Geometry ribbon, click the Wrap > Leak Detection tool.
Select the parts to be checked for leaks.
Optional: Click on the guide bar to define
seed radius.
Select enclosed seed nodes.
Click on geometry to place a node then click on the node itself to reposition
it inside of the selected part(s).
Enclosed nodes should be completely inside
the enclosure of interest.
Select target seed nodes.
Target nodes should be positioned in space outside of the selected part(s) and
along known leak areas.
You can select multiple target points to find multiple
paths.
Set the leak search size in the microdialog.
Any gaps bigger than search size will be flagged.
Click Check.
Once leaks are found, review the paths and close the leaks using the Wrap > Cap tool or the Surfaces > Patch tool.
The leak path is stored in a part called "_leak path". You can delete it once you are
done.
