Creating Surface Analysis Connections

This task shows you how to create a Surface Analysis Connection.
Surface analysis connections are used for simulating welding surface onto parallel faces, on an assembly model.
  • Only available with the Generative Assembly Structural Analysis (GAS) product .
  • The connection has to connect two bodies (2D or 3D).
  • Multi-selection is not available.

Open the sample11.CATAnalysis from the samples directory.

  1. Click Surface Analysis Connection in the Analysis Supports toolbar.

    The Surface Analysis Connection dialog box appears.

    • Name: lets you change the name of the connection.
    • First component: lets you select the first "side" of the part that will support the connection.
      • Multi-selection is not available.
      • You can select a 2D body, 3D body or a mesh part as support.
      • Select Mesh Parts: this button is available only if a support is selected.
        For more details, refer to Selecting Mesh Parts.
    • Second component: lets you select the second "side" of the part that will support the connection.
      • Multi-selection is not available.
      • You can select a 2D body, 3D body or a mesh part as support.
      • Select Mesh Parts: this button is available only if a support is selected.
        For more details, refer to Selecting Mesh Parts.
    • Surface: lets you select the welding surface.
      • Multi-selection is not available.
      • You can only select a 2D body as adhesive surface.

  2. Select the first component.

    In this particular example, select Support.1 - Fill.4.

  3. Activate the Second component field.

    To do this, select the Second component edit box as shown below:

  4. Select the second component.

    In this particular example, select Support.2 - Fill.3.

  5. Activate the Surface field.

    To do this, select the Surface edit box as shown below:

  6. Select the desired surface.

    In this particular example, select Surface.1 - Fill.2 as shown below:

  7. Click OK.

    The Surface Analysis Connection.1 connection appears in the specification tree under the Analysis Connection Manager.1 set.
