Cap Openings

Use the Wrap: Cap tool to close the openings of the wrap input and avoid leaks in the wrap result.

The Wrap tool works 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.

  1. From the Geometry ribbon, FE Geometry tools, click Wrap > Cap.


    Figure 1.
  2. Perform automatic capping.
    1. On the guide bar, switch the selector to Parts/Surfaces.
    2. Select parts/surfaces.
    3. Optional: On the guide bar, click to define cap options.
    4. Define the maximum patch width.
      Tip: Measure the hole length you want to close and define it as max width.
    5. Click Cap on the guide bar to fill caps.
    6. Review patches and delete any surface patches that are not required.


    Figure 2.
  3. Perform interactive capping.
    1. On the guide bar, switch the selector to Lines/Nodes.
    2. Select lines/nodes.
      Since the created caps do not need to be conformal, you can select any nodes or lines that cover openings.
    3. Optional: On the guide bar, click to define cap options.
    4. Click Cap on the guide bar to fill caps.

Access
Go to Geometry > Wrap > Cap.

Options

Consider feature loops
Consider feature edge loops for capping. If off, only free edge loops are capped.
Patch in separate collector
Organize newly created patches in a separate part.
Remesh after cap
Remesh neighboring region of capped surfaces. Turn on if input surfaces has good quality mesh.
During remeshing, element size, type, and order is determined by the surrounding element's size and type.
