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 Enclosure tool can generate a watertight manifold model from dirty input with considerably less manual work.

In order to precisely capture desired features and shape, the Enclosure tool has the capability to detect leaks, define size/proximity controls, and run enclosing.
