Create Lids

In the case of internal analysis Flow Simulation can analyze fluid flow only in a fully enclosed volume. So, before analyzing you may sometimes need to change geometry and close all the model’s openings by lids. This tool allows you to create those lids automatically.

Restrictions and Limitations

  • Note, that if you change an opening, the lid will not automatically change with it, you have to recreate the lid.

Procedure

  1. Open the Create Lids  dialog:
    • On the ribbon, click Flow Simulation > Tools > Create Lids.

    • On the toolbars, click Create Lids on the Flow Simulation Main toolbar.

    • In the menu, select Tools > Flow Simulation > Tools > Create Lids.

    Tip

    Also you can open the Create Lids dialog from the Check Geometry pane or the Leak Tracking pane by clicking Open Create Lids .

    In the Check Geometry pane, this option is available, if Check Geometry dialog is closed and the Check Geometry pane is kept visible. See “Check Geometry”.

  2. Under Selection:
    • Select the Planar Faces the Openings Belong to . If there are no such faces, you will have to make the lids manually.

    • If necessary, you can adjust the lid's thickness, by clicking the Adjust Thickness  icon and inputting value in the Thickness box.

    Note:

    Lids will be created for all holes located within the bounding box of the selected planar faces. So some lids may be outside of the selected faces.

  3. Click OK .

Results

If you are working with an assembly, the new LID1...LIDN parts will be created. If you are working with a single part, the new LID1...LIDN features will be created.

Tip

To ensure that the geometry is ready for analysis you can use Check Geometry tool (see “Check Geometry”).
