Define Interface Surfaces

Use the Interface Surface tool to define an interface for moving mesh. Optionally, this tool allows you to define topological baffle surfaces as an interface surface.

It is recommended to keep interface (internal) surfaces defined as autowall. This tool is intended for very specific use cases:
  • If you want to define baffles as interface surfaces.
  • If you want to define specific gap search parameters.

An interface can be defined on a topological interface surface, and optionally, on a topological baffle surface, based on simulation needs. During the solver run, interface surfaces will be split into two faces, and results will be available on both sides.

  1. From the Motion ribbon, click the arrow next to the Constraints tool set, then select Interface Surface.
    Figure 1.

  2. Select an interface surface.
    If the Include baffle surface option is active, you can select topological interfaces and baffles; the rest of the surfaces turn transparent. Turn off this option to select topological interface surfaces only.
  3. In the microdialog, define gap search parameters.
    Gap parameters are useful when you have a non-conformal interface between solids.
    You also have the option to split the interface surface or not.
    Note: For some non-moving interface faces, you may want to avoid splitting.
  4. From the guide bar, execute the command in the following ways:
    • Click to confirm your selection and remain in the tool.

      This allows you to continue creating instances and helps you visualize and edit instances with the legend.

    • Click to confirm your selection and exit the tool.
