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: Cap tool to
close the openings of the wrap input and avoid leaks in the wrap result.
The
Wrap tools work for tessellated geometry. If the input
is b-spline geometry, first convert to discrete geometry using the Convert tool.
To prepare for wrap and get a manifold model, it is good practice to close openings
like pipe ends and cover unnecessary features like slots so that they are not
captured in wrap results, as they are not useful for analysis. The Wrap: Cap tool provides the
capability to automatically or interactively create caps or patches.
From the Geometry ribbon, click the Wrap > Cap tool.
Perform automatic capping.
On the guide bar, switch the selector to
Parts/Surfaces.
Select parts/surfaces.
Optional: On the guide bar, click to define cap
options.
Define the maximum patch width.
Tip: Measure the hole length you want to close and define it
as max width.
Click Cap on the guide bar to fill caps.
Review patches and delete any surface patches that are not
required.
Perform interactive capping.
On the guide bar, switch the selector to
Lines/Nodes.
Select lines/nodes.
Since the created caps do not need to be conformal, you can select any
nodes or lines that cover openings.
Optional: On the guide bar, click to define cap
options.
