Select Connected Faces

Geometry > Face > Select Connect

Dialog Box

Input can be from the FE model or Parasolid model imported with "Save geometry in the database" option enabled.

Surfaces connected to an element, Surfaces connected to a face

These options identify closed regions, excluding non-manifold edges.

Select from visible faces

If this toggle is ON, the tool will consider only visible faces.

Example

Select an element or a face.

It will show the connected faces and make other faces as transparent. Users can create a group or a body for the shown faces.

The inverse of the above output is shown below for better understanding.

This tool is mainly used for the following purposes:

  • The fluid volume in a manifold assembly can be extracted in a single click if all the openings are closed.

  • In CFD modeling, to extract the car body outer surfaces.
  • It also helps in verifying whether the connected faces are watertight or not.

Bodies outer surfaces

This option extracts the outer faces of the given body. It will create two face groups, one for outer faces and another for inner faces.

Delete inner surfaces

If this toggle is ON, it will delete all the inner faces.

Example

Bodies inner surfaces

This option extracts the fluid flow surfaces of the given body. It will create a group for the identified inner faces.

Delete outer surfaces

If this toggle is ON, it will delete all the outer faces.

Example

Input body

The below image shows the extracted fluid flow surfaces for the input body:
