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.
